Question

Which of the following is a common design component shared between conventional stove elements, microwave ovens, and induction heating plates?

Select one:

a. Electrons lose energy and resistive heating takes place.

b. A copper wire coil that heats up when current passes through it.

c. A time varying magnetic field produces heat.

d. None of the answers are correct.

Answer 1

Option a is not correct because electrons are not responsible for heating in all the cases. For example in microwave oven, polar molecules produces heat.

Option b is also not correct since this type of design is only available in conventional stoves.

This is incorrect as this method is only used in induction heating plates.

so None of the answers are correct.
