Hi Prachis, as we know that according to ohms law current=potential diff./resistance and we also know aluminium has less resistance than nichrome.current will be more in aluminium.
Heat =current ×current ×resistance ×time .
U can calculate heat by putting values of resistance and current.
Thank u and always help who are in need.
prachiss:
but in question there is copper wire.
So sorry Prachis I misunderstood .
Take copper instead of aluminium and copper is even good conductor than alumimium. So less resistance of copper than nichrome
ohkkk
tq so much
