## Homework Statement

## Homework Equations

Kirchoff's Voltage Law - Sum of voltages = 0

Kirchoff's Current Law - Net Sum of Currents going into a node = 0

V = IR

## The Attempt at a Solution

I am not sure if I am doing this correctly, could someone please check my work?

Sum of I net at node B = - I

_{2}- 8A + 5A = 0

I

_{2}= -3A (3A but in the opposite direction from the arrow drawn)

Sum of V

_{ABFH}= -(5Ω*I

_{2}) - V

^{1}= 0

-5Ω*-3A - V

_{1}= 0

V

_{1}= 15 V

Sum of VDEFG= -(I3*5Ω) + 50V - V

_{1}= 0

-5*I

_{3}+ 50V - 15V = 0

I

_{3}= 7A

I am particularly concerned if I am treating the ampmeter or voltage meter right (Do I need to account for their inside resistance?) and whether or not I am using the correct signs.

Thank you for your help.
