Question

2 resistors of 7ohm and 3ohm are connected in parallel. Four such combinations are connected in series. Calculate the equalent resistence of the combination

Answer 1

HELLO DEAR FRIEND

given resistance = 7ohm and 3ohm

1/Rp 1/7 + 1/3

Rp = 21/10

given that Four such combinations are connected in series.

Then the equalent resistence of the combination = 4 × 21/10

$\huge \boxed{8.5ohm } \small{ans}$

HOPE IT HELPS YOU DEAR FRIEND THANKS
