Question

derive the formula for calculation of work done when current flows through a resistor.

Answer 1

H=I2RT is the formula of work done when current flows through a resistor

Answer 2

There's a formula : W = Q x V;

where W stands for wokrdone, Q stands for charge and V stands for potential.

Now, from ohm's law we know, V =I x R; where I and R are current and resistance respectively.
