Question

when electric current is passed through a metallic conductor, amount of heat produced in the conductor depends on its..??​

Answer 1

heat produced in the conductor, H ∝ i²Rt

from Joule's law of heating,

when electric current passing through a metallic conductor of resistance R for time t, heat produced in the conductor depends on,

• current ; heat is directly proportional to square of current passing through conductor.
• resistance ; heat is directly proportional to resistance of conductor
• time, heat is directly proportional to time.

i.e., H ∝ i²Rt

H = i²Rt, [ proportionality constant = 1]

hence, heat produced in the conductor is given as i²Rt

Answer 2

$\huge\bold\purple{Answer:-}$

The amount of heat produced in current conducting wire, is proportional to the square of the amount of current that is flowing through the circuit, when the electrical resistance of the wire and the time of current flow is constant.
