Question

State and derive joules law

Answer 1

please follow the attachment

Answer 2

Joule Law states that the heat generated in a conductor is directly proportional to the
1)square of the current flowing in the circuit.
2)resistance of the conductor
3)time for which the current flows in the conductor.
$h = {i}^{2} rt$
where h= heat generated
i=current
r = resistance
& t = time for which the current flows

Derivation is answered above.
Thank you hope this helps.
