Question

In the arrangment of resistances shown below, the
effective resistance between points A and B is

(1) 20
(2) 30
(3) 90
(4) 110 ​

Answer 1

Answer:110 ohm

Explanation: resistance in series=R1+R2+. .. ..

Resistance in parallel =1/R1+1/R2+.....

By substituting the answer is 110

Answer 2

Answer:

(4)

Explanation:

110 ohm(resistance)
