Question

write and explain any 2 ways by which the electric current can be doubled without changing the temp and conductor?​

Answer 1

Answer:

We know H = Isquare * R *T

now given that R dash = 2 times of old R

we apply in the above formula And we are also given that remaining current and time remain unchanged

H dash = I square * 2 R * T

H dash = 2 * of H
