Answer:
Heat,

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

Using the formula
Heat,

Heat,

Hence, the the expressions for the heat produced per second in a resistor in terms of current and resistance is given by
Heat,
