Question

54. The total resistance of the circuit when three resistors 2o ohm each which are connected in
series is​

Answer 1

Explanation:

As I suppose you are asking 2 separate question so

If 3 resistance of 2 ohm are connected in series will have equivalent resistance Req=R1+R2+R3=2+2+2=6 ohm

and for parallel-

Req=R/no of register ( if all have same resistance)

So ,Req=2/3 ohm.
