For the circuit given below, the Kirchoff's loop rule for the loop BCDEB is given by the equation
(1) –i2R2 + E2 + E3 + i3R1 = 0
(2) –i2R2 + E2 – E3 + i3R1 = 0
(3) i2R2 + E2 – E3 – i3R1 = 0
(4) i2R2 + E2 + E3 + i3R1 = 0

Ans: (3) i2R2 + E2 – E3 – i3R1 = 0
Sol. In a loop BCDEB by KVL
VB – i2R2 – E2 + E3 + i3R1 = VB
i2R2 + E2 – E3 – i3R1 = 0
For the circuit shown in the figure, the current I will be (1) 0.5 A (2) 0.75 A (3) 1 A (4) 1.5 A
