Question

A wire of resistance R is cut intofive equal pieces.
These five pieces of wire are then connected in parallel.
If the resultant resistance of this combination be R,
then the ratio R, :R, is:
(a) 5
(b) 1/5
(C)25
(d)1/25​

Answer 1

Explanation:

The reciprocal of equivalent resistance of the resistors connected in parallel is the sum of the reciprocals of the individual resistances.. And in parallel connection voltage is constant, current varies.
