Due to skin effect the resistance in D.C. supply is :
Equal to A.C.
More than A.C.
Less than A.C.
Zero
Less than A.C.
Skin effect reduces the effective cross - section of the conductor and thus increases its effective resistance.
Skin effect is directly proportional to the frequency. So in DC, frequency is zero then skin effect is zero. Thus due to skin effect the resistance in DC supply is less than AC supply
