29) In the circuit shown below, answer the following questions R1 R3 422 12 B - 28 V 2 Ω R₂ 7V – B2 a) Write the equations -

Answer 1

R1 T_2 R3 4Ω 11 1Ω T_1 - 1_2 Β-28V 2Ω R, 7ν – B2

Assume I₁ to be the current in first loop and I₂ to be the current in second loop both in clockwise sense we have,

So the current in middle branch will be I₁ - I₂.

The equations can be written as

B₁ - I₁R₁ - (I₁ - I₂)R₂ = 0 ............(i) { from first loop}

-B₂ - I₂R₃ + (I₁ - I₂)R₂ = 0 ..............(ii) { from second loop }

Upon solving these equations you will get

I₁ = 5A

I₂ = 1A
