Question

9) 2 idential resister of 5ohm are first connected
in series and then in

parallel find the ratio of equivalent resistance
in two cases.​

Answer 1

1. in series

5+5 = 10 ohm

in parallel

1/5+1/5=2/5

equivalent resistance :-

10/2/5=10*5/2=25ohm

Answer 2

ANSWER :-

ratio of series : ratio of parallel

=> 2 : 1
