Question

(ii) Find the equivalent resistance between A and B..​

Answer 1

Answer:

4ohm

Step-by-step explanation:

ae we know Req=R1+R2+R3. in series connection

and 1/Req=1/R1+1/R2+1/R3

SO, in parellel connection

1/Req=1/2+1/2

1/R=1

R=1. (1)

Now in series connection

R=R1+R2+R3

R=1+2+1. from(1)

Therefore,total resistance is 4ohms
