P 3.2-2 Determine the values of i2, i4, v2, v3, and v6 in Figure P 3.2-2.

 

 

is found using a junction rule.  Consider the junction where parts A, B, and C meet.

 

Solving for

 

Similarly is found considering the junction where parts C, D, and E meet

 

Solving for

 

To find , we will use voltage loop rules.  So consider the loop made of parts A and B the voltage around the loop must equal zero so, starting at lower left corner and going clockwise around loop produces:

 

 

Note: positive terms are going from – terminal of part to +, otherwise you should subtract.  Solving for

 

For  we can do loop made of parts B, C, and D.  Again start at lower left and go clockwise

 

Solving for

 

 

For  we can do loop made of parts D, E, and F.  Again start at lower left and go clockwise

 

Solving for

 

To check answers calculate total Power of circuit Start at far left and go in alphabetical order.

 

 

As it should, it totals zero!!
