Step 1
Magnetron
Answer
The magnetron is a key component in a microwave oven that converts electrical energy into microwave energy or electromagnetic waves. It functions by using a direct current (DC) voltage to generate microwaves through a process called thermionic emission, where electrons are emitted from a heated cathode and are then propelled towards an anode, producing microwaves in the process.
Step 2
Transformer
Answer
The transformer in a microwave oven is responsible for increasing the domestic voltage, typically from 230V, to a higher voltage necessary for the operation of the magnetron. This is achieved by stepping up the voltage using electromagnetic induction, allowing the microwave to generate sufficient energy to produce microwaves.
