ANSWER

The equivalent circuit diagram shows that the series combinations of the resistances in the circuit are:

15Ω & 10Ω , 40Ω & 10Ω . 20Ω & 30Ω

These three combinations are connected in parallel to each other.

So, equivalent resistance of the parallel combination will be:

Rp1=251+501+501

Now, this equivalent resistance is in series with 2Ω and 8Ω resistances.

∴Req=2Ω+Rp+8Ω

Req=2+⎝⎜⎜⎜⎛251+50
