Resolved Question: components of a toaster.. physics?
In nearly every kitchen household, there would be an automatic pop-up toaster. The toaster, which was originally invented in 1893 in Great Britain by Crompton and Co., got reinvented in 1909 but the toaster would only toasted one side of the bread at a time and had to be manually turned off. The automatic toaster was then invented in 1919 by Charles Strite.

When using a toaster, people aren’t aware that it is an electrical device. Each basic toaster nowadays has these main components; an electromagnet to hold the toaster handle down, nichrome wires that are wrapped around a mica sheet which uses infrared radiation to toast the bread, a capacitor to store energy to the toaster, a rectifier which changes AC to DC and a potentiometer which is the timer for how long the bread stays in the toaster.

When the toaster handle is pulled down, a plastic bar presses on a switch and applies power to the toaster. When this happens, a piece of metal which is also in the handle gets attracted to an electromagnet. The electromagnet has an electric current running through it which creates a magnetic field.

The electromagnet has one main purpose, to release the handle when the power gets switched off, this happens when the potentiometer has reached the time of toasting the bread.

The potentiometer in a toaster is the dial on the side with the minutes of how long the bread gets toasted. When the power to the toaster gets activated, it turns of the nichrome wires. The nichrome wires can reach up to a maximum of 650 degrees Celsius, which is how the bread gets toasted by the heat.

Nichrome wires are wound on a strip of mica, as it can withstand the heat the nichrome produce.

When a toaster gets plugged into a socket, it has three wires; an earth wire (yellow/green), a neutral wire (blue) and an active wire (brown). Each of these wires has a different purpose.

The earth wire, which leads to a connection into the ground through the main electrical system of the house, is to prevent electric shock from insulation faults, the active wire carries the voltage from the source of power to the toaster and the neutral wire carries it back.

i wrote that above… i need to know what else is in a toaster.. help sooo much ten points easy

Lockheed AC-130A/H Spectre/AC-130U Spooky AC-130A Spectre
The A-model gunship was the first AC-130 model. The aircraft is 97 feet 9 inches long and 38 feet 3 inches tall. It has a wingspan of 132 feet 7 inches and a wing area of 1,745 sq. feet. Initially, the C-130 had a maximum speed of 384 mph and an unrefueled range of 2,450 miles with maximum load. However, with the aerial refueling modification, the range for the later model gunships was only limited by crew endurance.
The high-wing design of this aircraft and its large capacity made it especially suited as a gunship. The first gunship, the AC-47, with low wings, reduced its field of fire. Having the guns below the wings eliminated the basic problem of the AC-47. Also, the large C-130 could carry more ammunition for its heavier weapons. The AC-47 was equipped with three 7.62mm miniguns. In contrast the AC-130A carried 7.62mm and 20mm weapons; the AC-130H fired 20mm, 40mm and 105mm guns; and the newest gunship, the AC-130U, is equipped with 25mm, 40mm and 105mm weapons.
The C-130 gunship was a new weapon system in an old airframe. Therefore, there were a number of firsts that one model or another chalked up for the gunship. Spectre was operationally tested at Eglin Air Force Base, Fla., from June to September 1967. It initially deployed to Nha Trang, Republic of Vietnam Sept. 20, 1967, and flew its first combat mission Sept. 27. Its first truck busting mission was flown Nov. 8, 1967, and all A-model gunships were assigned to Detachment 2, 14th Commando Wing. In 1968, Det. 2 was assigned to the 8th Tactical Fighter Wing and became the 16th Special Operations Squadron. At that time the C-130A was renamed the AC-130A.
AC-130H Spectre
The Vietnam-era AC-130E “Pave Spectre” was an improved version of the AC-130A “PAVE PRONTO” aircraft. The C-130E was equipped with more powerful versions of the Allison T56 turboprop engines. The AC-130E was later upgraded to AC-130H standards under project “Pave Spectre II”
The AC-130 is an excellent fire support platform with outstanding capabilities. With its extremely accurate fire control system, the AC-130 can place 105mm, 40mm and 25mm munitions on target with first round accuracy. The crew of these aircraft are extremely proficient working in military operations in urban terrain [MOUT] environments. Many ground units have begun to use Infra-red (IR) tape either as arm bands or sewn to the top of their ballistic helmet for marking troops and vehicles, especially when working with the AC-130. It only takes a very small piece of IR tape to be distinguished as friend or foe by an AC-130, and anything larger than a one inch by one inch piece is going to white out a large portion of the monitor aboard the aircraft.
AC-130U Spooky
Continuing the distinguished combat history of side-firing AC-130 gunships, the new AC-130U Spectre gunship was fielded as a replacement for the AC-130A aircraft and to supplement the AC-130H gunship fleet. Its mission is to support conventional and joint special operations forces any time, any place. The AC-130U Gunship program initially consisted of 13 [later 17] new Lockheed C-130H airframes, modified by Boeing, which assumed responsibility for the AC-130U contract when it merged with the Rockwell Corporation, the original contractor on the program. The modifications allow the aircraft to perform the full range of special operations and conventional gunships missions. It provides surgical firepower, night and adverse weather operations, and extended loiter time on target in Special Operations Forces (SOF) and conventional roles. The AC-130U is named for the AC-47D and has the “Spooky” nickname rather than the “Spectre” nickname used by all other AC-130 gunships.
The AC-130U was armed with a 25mm Gatling-gun (capable of firing 1800 rounds per minute), a single-barrel, rapid-fire 40mm Bofors cannon, and a 105mm Howitzer. The AC-130U replaced the two 20mm cannon used on the AC-130H with one trainable 25mm cannon while retaining the other weapons. The AC-130U employs the latest technologies and can attack two targets simultaneously.
The U-model gunship is one of the most complex aircraft weapon systems in the world today, containing more than 609,000 lines of software in its mission computers and avionics systems. Although it still uses the venerable Lockheed C-130 airframe, the AC-130U incorporates the latest sensor technology, along with an entirely new fire-control system, to substantially increase the gunship’s combat effectiveness. The fire control system offers a dual-target attack capability, whereby two targets up to one kilometer apart can be simultaneously engaged by two different sensors, using two different guns. All light-level television, infrared sensors, and the Hughes APQ-180 radar (also found on the F-15E Strike Eagle) provide night and adverse weather capability. The strike radar provides the first gunship capability for all weather/night target acquisition and strike.
The AC-130U is an excellent platform for working at night. The pilots are proficient with NVGs and the AC-130 carries various systems for working in the dark including FLIR, and LLTV. It has an LST and two laser designators, although these systems cannot be cued to each other. The APQ-180 fire control radar gives the AC-130 an adverse weather capability. They orbit at approximately 5,000-10,000? AGL around a target area in a 5 nm arc. AC-130U strengths include an excellent loiter time of up to 4 ½ hours. It is a superior platform for Troops in Contact (TIC), and is best used at night to optimize all of its sensors. It also has a superior communications suite. AC-130U weaknesses include decreased maneuverability and survivability in a high tech surface-to-air threat environment. It is a large target with slow speed and should not be used in a high threat environment in daylight. It also has a wide orbit pattern.
All weapons can be slaved to sensors which permit night or adverse weather operations. The AC-130U is a highly integrated weapons system. Within the AC-130U resides the Battle Management Center (BMC) where crew coordination is critical to the success of their missions. This BMC consists of five crew stations which are the Navigator (Nav), Fire Control Officer (FCO), Electronic Warfare Officer (EWO) and two Sensor Operators who control the Infrared Detection Set (IDS) and the All Light Level Television (ALLTV) systems.
To enhance survivability, emphasis has been placed on increasing the stand-off range of the gunship’s weapons system and improving first-shot accuracy. In addition, a set of electronic countermeasures has been installed to help defend the AC-130U against modern threats. The AC-130U gunship airframe is integrated with an armor protection system (APS).
