Problem: Use Kirchhoff's rules to find the current in each of the three resistors in the circuit shown. Also calculate the voltage drop across all three resistors.

FREE Expert Solution

Using Kirchoff's junction rule at A:

i1 + i2 = i3 

For the top loop counterclockwise:

4.0 - 16i1 + 18i2 - 12 = 0

Multiply by -1 and simplify

16i1 - 18i2 + 8 = 0  Eqn 1

For the lower loop counter-clockwise:
