1.Easy
R1​ = 3 ΩR2​ = 2 Ω+−V1​12 VR3​6 ΩAR4​8 ΩBI1​I2​

Use mesh analysis to find the mesh current I2 (clockwise).

V1 = 12 VR1 = 3 ΩR2 = 2 ΩR3 = 6 ΩR4 = 8 Ω
I2 = A
2.Easy
R1​ = 2 ΩR2​ = 10 Ω+−V1​20 VR3​12 ΩAR4​5 ΩIR4​BI1​I2​

Use mesh analysis to find the current IR4 through R4 in the direction of the arrow.

V1 = 20 VR1 = 2 ΩR2 = 10 ΩR3 = 12 ΩR4 = 5 Ω
IR4 = A
3.Medium

Use mesh analysis to find the voltage VR1 across R1 with the polarity shown.

V1 = 6 VV2 = 15 VR1 = 12 ΩR2 = 5 ΩR3 = 8 Ω
VR1 = V
4.Medium
R1​ = 2 ΩR2​ = 4 ΩIR2​+−V1​9 VR3​5 ΩA+−V2​9 VI1​I2​

Use mesh analysis to find the current IR2 through R2 in the direction of the arrow.

V1 = 9 VV2 = 9 VR1 = 2 ΩR2 = 4 ΩR3 = 5 Ω
IR2 = A
5.Hard
R1​ = 6 ΩR2​ = 5 ΩR3​ = 12 Ω+−V1​36 VR4​2 ΩAR5​12 ΩB+−V2​36 VI1​I2​I3​

Use mesh analysis to find the mesh current I1 (clockwise).

V1 = 36 VV2 = 36 VR1 = 6 ΩR2 = 5 ΩR3 = 12 ΩR4 = 2 ΩR5 = 12 Ω
I1 = A
6.Hard
R1​ = 3 ΩR2​ = 5 ΩR3​ = 30 Ω+−V1​15 VR4​5 ΩAR5​25 ΩB+−V2​10 VI1​I2​I3​

Use mesh analysis to find the mesh current I3 (clockwise).

V1 = 15 VV2 = 10 VR1 = 3 ΩR2 = 5 ΩR3 = 30 ΩR4 = 5 ΩR5 = 25 Ω
I3 = A
