Question

This Iis problem 51 from chapter 3 of the course text with modifications. Considering the circuit of the figure in the link provided above, define a counter-clockwise-circulating current loop in the middle loop of the circuit as i1 and also define another counter-clockwise-circulating current loop in the right-most loop of the circuit as i2. The current i_x is to be defined as the current running across the vertical 20 Ohm resistor, from the node labeled "Va," across the 20 Ohm resistor, towards the bottom node. Determine current i1. http:/i.imgur.com/K3fOexq.jpg Show all work

Explanation / Answer

Sry... I3 is not -100 A but -100 mA. Thus use I(3) = -0.1

Thus second eqn is 10 I(1) - 40I(2) = 3 -------------eqn(2)

Solve eqn(1) and (2)

I(1)= -0.38 A and I(2) = -0.17 A
