Question

35. Two metal wires of identical dimension
connected in series. If o, and on are the conductivi
of the metal wires respectively, the effective
conductivity of the combination is :-​

Answer 1

Explanation:

If the conductivity of the wires are C1 &C2 and the effective conductivity the wires are C' then,
