How do you solve this problem?

Explanation:

The principle of continuity of current demands that

.

And applying Kirchhoff's current law two two loops in the circuit, we get:

(1).

and

(2). .

Since , equation (1) becomes

Since

From equation (2) we now get:

Finally, we solve for

therefore, the resistance is

The potential drop is

Similarly,  the potential drop is

The total resistance of the circuit is  

where

;

therefore,
