(a) The quantity of charge that flows through the circuit in 5 minutes is :
(i) 10C (ii) 60 C
(iii) 600 C (iv) 60
(b) What is the resistance of the device?
(c) Calculate the power of the heating device.​

Answer 1

Answer:

Dielectric heating

A non-conducting material generates heat when subjected to an alternation electric field. This process wherein heating takes place due to dielectric loss is known as dielectric heating. ... If an ac voltage is applied across a piece of an insulator, an electric current i flows as shown in Fig.
