Explanation / Answer

Let I1,I2 and I3 are currents through R1,R2 and R3.

Apply, KVl in left loop,

-I3*R3 + I2*R2 = 0

7*I2 - 3.6*I3 = 0 ------(1)

Apply, KVL in right loop,

4 - I1*R1 + 4 - I2*R2 = 0

6.7*I1 + 3.6*I2 = 8 ----(2)

at the junction

I1 = I2 + I3 ---(3)

on solving the above 3 equations

we get

I2 = 0.343 A

I3 = 0.667 A

I1 = 1.01 A

so

a) I3 = 0.667 A

b) power deliverd to R3, P3 = I3^2*R3

= 0.667^2*3.6

= 1.6 W
