Question

193. Find the effective resistance between points A
and B

(1) 7.5 Ω
(2) 10.5Ω
(3) 12.5 Ω
(4) 14.5 Ω
​

Answer 1

Answer:

ans :-7.5Ω

Explanation:

Req b/w 3,6ohm is

$\frac{1}{req} = \frac{1}{3} + \frac{1}{6}$

Req=2Ω

Req b/w 2,8Ω is

$req =2 Ω + 8Ω$

Req=10Ω

Req b/w 10,30Ω is

$\frac{1}{req} = \frac{1}{10} + \frac{1}{30}$

Req=7.5Ω

Therefore,equivalent current is 7.5Ω
