Establish the relation that heat produced in a metallic conductor due

1.	Establish the relation that heat produced in a metallic conductor due to the flow of current is V2t/R joules, where V is the potential difference across the ends of the conductor, R its resistance and t is the time in second for which current flows.
Answer» From the relation Q = vit joule Applying ohm's law, V = iR or i = V/R Substituting the value of i, we get Q = V.(V/R)t = V²t/Rjoule.

Answer»

From the relation

Q = vit joule

Applying ohm's law, V = iR

or i = V/R

Substituting the value of i, we get

Q = V.(V/R)t = V²t/Rjoule.
