The effective resistance of a conductor will be the same as ohmic resistance when
current is in
true sine wave form
voltage is
low
power factor
is unity
current is uniformly distributed in the conductor cross-section
current is uniformly distributed in the conductor cross-section
In general
If current distribution is uniform then RAC = RDC .
Hence, the
correct option is (D).
