Part 2: Kirchhoff's Rules For the circuit shown below, the directions of the currents through the circuit elements has been chosen arbitrarily. Using Kirchhoff's rules, you will determine the actual currents through the circuit elements. (Yes, this circuit could be analyzed using equivalent resistance, but don't do it that way.)
