1.Easy
R1​ = 10 ΩR2​ = 12 ΩIR2​+−V1​10 VR3​8 ΩAR4​10 ΩBI1​I2​

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

V1 = 10 VR1 = 10 ΩR2 = 12 ΩR3 = 8 ΩR4 = 10 Ω
IR2 = A
2.Easy
R1​ = 6 Ω+−VR1​R2​ = 10 Ω+−V1​18 VR3​5 ΩAR4​2 ΩBI1​I2​

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

V1 = 18 VR1 = 6 ΩR2 = 10 ΩR3 = 5 ΩR4 = 2 Ω
VR1 = V
3.Medium
R1​ = 12 ΩR2​ = 12 Ω+−V1​30 VR3​15 ΩIR3​A+−V2​9 VI1​I2​

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

V1 = 30 VV2 = 9 VR1 = 12 ΩR2 = 12 ΩR3 = 15 Ω
IR3 = A
4.Medium
R1​ = 15 ΩR2​ = 2 Ω+−V1​15 VR3​8 ΩA+−V2​24 VI1​I2​

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

V1 = 15 VV2 = 24 VR1 = 15 ΩR2 = 2 ΩR3 = 8 Ω
I1 = A
5.Hard
R1​ = 12 ΩR2​ = 15 ΩR3​ = 8 Ω+−V1​10 VR4​2 ΩAR5​15 ΩB+−V2​9 VI1​I2​I3​

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

V1 = 10 VV2 = 9 VR1 = 12 ΩR2 = 15 ΩR3 = 8 ΩR4 = 2 ΩR5 = 15 Ω
I2 = A
6.Hard
R1​ = 20 ΩR2​ = 2 ΩR3​ = 25 Ω+−V1​6 VR4​15 ΩAR5​30 ΩIR5​B+−V2​36 VI1​I2​I3​

Use mesh analysis to find the current IR5 through R5 in the direction of the arrow.

V1 = 6 VV2 = 36 VR1 = 20 ΩR2 = 2 ΩR3 = 25 ΩR4 = 15 ΩR5 = 30 Ω
IR5 = A
