Question

A certain amount of current is passed through a conductor. Now the
potential difference is made thrice keeping the resistance and time of
flow unchanged. What will be the heat produced by the conductor?​

Answer 1

let current passed through conductor be I

the pd across conductor be V

resistance of conductor be R

heat = power/time = VI/t

new pd across conductor is 3V

so heat produced will be = 3VI/t

Thus the new heat produced will be 3 times the heat produced by conductor previously

Answer 2

Answer:

3 times of heat produced.
