Find V and ISolution 3W and 3W are in parallel it can replac

Solution

3W and 3W are in parallel it can replaced by

3*6/(3+6) =2W

algebraic sum of the emfs in a closed loop is 0

14 - 7*I - 2*I - 4*I = 0

I = 14/13 = 1.08 A.

no current flows through 12W, hence Voltage at the end of 12W is same as at the junction of 4,3,6 and 12 ohms

3 and 6 ohms are in parallel potential drop across the combination

V = 1.08 * 2 = 2.16 V
