1.Easy
R1​ = 2 ΩR2​ = 5 Ω+−V1​15 VR3​8 ΩAR4​10 ΩIR4​BI1​I2​

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

V1 = 15 VR1 = 2 ΩR2 = 5 ΩR3 = 8 ΩR4 = 10 Ω
IR4 = A
2.Easy
R1​ = 6 ΩR2​ = 12 Ω+−V1​6 VR3​12 ΩAR4​12 ΩBI1​I2​

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

V1 = 6 VR1 = 6 ΩR2 = 12 ΩR3 = 12 ΩR4 = 12 Ω
I2 = A
3.Medium
R1​ = 12 ΩR2​ = 8 Ω+−V1​18 VR3​10 ΩIR3​A+−V2​9 VI1​I2​

Use mesh analysis to find the current IR3 through R3 in the direction of the arrow.

V1 = 18 VV2 = 9 VR1 = 12 ΩR2 = 8 ΩR3 = 10 Ω
IR3 = A
4.Medium
R1​ = 5 ΩR2​ = 10 ΩIR2​+−V1​6 VR3​10 ΩA+−V2​9 VI1​I2​

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

V1 = 6 VV2 = 9 VR1 = 5 ΩR2 = 10 ΩR3 = 10 Ω
IR2 = A
5.Hard
R1​ = 30 ΩR2​ = 5 ΩR3​ = 25 Ω+−V1​36 VR4​6 ΩAR5​12 ΩB+−V2​15 VI1​I2​I3​

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

V1 = 36 VV2 = 15 VR1 = 30 ΩR2 = 5 ΩR3 = 25 ΩR4 = 6 ΩR5 = 12 Ω
I1 = A
6.Hard
R1​ = 4 Ω+−VR1​R2​ = 6 ΩR3​ = 8 Ω+−V1​24 VR4​6 ΩAR5​30 ΩB+−V2​36 VI1​I2​I3​

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

V1 = 24 VV2 = 36 VR1 = 4 ΩR2 = 6 ΩR3 = 8 ΩR4 = 6 ΩR5 = 30 Ω
VR1 = V
