Question

Calculate the effective resistance between the points A and B in the network shown below in figure.

Answer 1

For parallel resistance

`1/"R" = 1/12 + 1/6 + 1/4`

= `(1+2+3)/12`

= `6/12`

R = 2 Ω

Now all the resistances are in series

R = 2 + 2 + 5

= 9 Ω

Hence, Effective resistance between A and B = 9 Ω
