Microwave ovens don't expose food to electric currents, they expose food to microwaves. Microwaves are a type of electromagnetic radiation, or a type of light. The only difference between visible light and microwaves is the wavelength of the light. Wavelength is what makes blue light look different from red light (red light is made of physically longer waves). Microwaves are much shorter than visible light and have much higher energy. That energy is used to heat up the water molecules in the food you put in the microwave. That's how it heats up your food.

Energy used to cook food in a microwave is a form of what energy?
Electric energy
What are the advantage and disadvantages of heating effect of current?
Disadvantages of the heating effect of electric currents are: short circuits, house fires, and explosions. Advantages of the heating effect of electric currents are: electric light, toasting food, and keeping a room warm.
What type of waves does toasters have?
Electric Toasters have microwave waves because microwave waves can penetrate food whereas infra - red waves cannot.
What exactly does an electric warming tray do?
An electric warming tray keeps food warm after it has been cooked. This helps to avoid the hassle of having to re-heat the food in the oven or microwave.
What happens to solid food when in the microwave to long?
If the microwave is not energized, then the food will spoil. If the microwave is energized, then the food will burn.
How a electric microwave works?
Most people would think that microwaves use heat to warm up the food, but that isnt true. As you know almost every food has traces of water. What a microwave does is it send microwaves which "excites" the water inside the food. When water is "Excited" it produces heat which warms up the food.
How do you cook food without gas?
You can use a microwave, electric hob, oven or even barbecue; all methods without using gas.
What is the difference between microwave and stove cooked food?
Microwave energy is electromagnetic (EM) radiation, and microwave ovens use energy at a frequency of about 2450 MHz (2,450 million cycles per second). This energy is in the microwave band of frequencies, hence the term microwave oven. The frequency is a good choice, because it is quite effective in causing dielectric heating in molecules in the food. This is because there are a lot of molecules within the food that will respond to the microwave energy. These molecules, because they have an electric dipole, will attempt to align themselves with the passing electromagnetic wave. They will be trying to turn back and forth at that 2450 MHz, and this generates heat, which warms/cooks the food.
How does cooking happen in a microwave?
When food is placed inside the microwave oven, the microwave released will 'agitate' the water molecules in the food, which causes heat to be produced, which then cooks the food.
Is sterilite microwave safe?
All of Sterlite food storage items are microwave safe. They are designed to reheat food in the microwave. Use caution when reheating food high in sugar or fat as they can cause damage to microwave safe containers. See microwave manufacturer's instructions for information regarding the use of microwave safe containers in your microwave."
Why you need a code at microwave to reheat food?
A person doesn't often need to enter a code at a microwave if they want to reheat food. They simply program the microwave for how long they want the food to cook after they place the food inside.
Can you leave plates of food to be eaten later on-top of a microwave if the microwave is used in the mean time will it not keep reheating the food on top of the microwave?
Microwaves should not be leaking from the microwave oven, however leaving food out and not refrigerated can be a health hazard in itself.
