Question

Write the relation between the heat produced H in a conductor of resistance R through which current I passes for t seconds

Answer 1

This is called Joule's law of heating.

All materials offer resistance to the flow of current through them. So some external energy is required to make the current flow. This energy is provided by the battery. Some of this energy gets dissipated as the heat energy, so the resistor becomes hot.

Work done in carrying a charge Q through a potential difference V is given as

Also, Q=IT

Using ohm's law, V=IR

W=I^2 RT

This work in carrying the charge through the wire appears as the heat produced i.e

H=VIT=I^2 RT

This energy is dissipated as heat energy

Hope, it helps

Answer 2

Answer:H=R upon

at least say honor relation between I,H,and T
