Question

 The effective resistance of a conductor will be the same as ohmic resistance when

A.

current is in true sine wave form 

B.

voltage is low 

C.

power factor is unity 

D.

current is uniformly distributed in the conductor cross-section

Answer ( Option D)

current is uniformly distributed in the conductor cross-section

Solution

In general  RAC< RDC due to non-uniform, current distribution of current AC in a conductor.

If current distribution is uniform then   RAC = RDC .

Hence, the correct option is (D).
