Explanation:
The Joule's law of heating states that the heat evolved in a conductor is directly proportional to the product of square of current and resistance. It is given by :
[tex]H=I^2Rt[/tex]
I is current
R is resistance
t is time
Ohm's law, V = IR
So,
[tex]H=\dfrac{V^2t}{R}[/tex]
V is voltage
