Answer:

Step-by-step explanation:
Let H be heat produced per sec
Time, t=1 sec
Resistance of resistor=R ohm
We have to write down the expression for the heat produced per second in a resistor in terms of potential difference and resistance.
We know that
Heat,

Substitute the value
Then, we get
Heat,


This is required expression for the heat produced per second in a resistor in terms of potential difference and resistance.
