Question
Consider the circuit shown below. Find V1 (in V), I2 (in A), and I3 (in A). (Due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in WebAssign. For the currents, indicate the direction with the signs of your answers.)

for I3 current
I3 = I1 + I2
= 6 + I2
KV L at left loop
V1 - I1 R1 + I2 R2 = 0
V1 - 18 X 6 + 9 I2 = 0
V1 + 9 I2 = 108
now KVL at right loop
V2 - I3 R3 - I2 R2 = 0
32 - ( 6 + I2 ) X 4 - 9 I2 = 0
32 - 24 - 4 I2 - 9I2 = 0
13 I2 = 8
I2 = 0.615 A
V1 + 9 I2 = 108
V1 + 9 X 0.615 = 108
V1 = 102.465 V
current I3 = 6 + 0.615 A
I3 = 6.615 A
