Problem B3:
Consider the circuit shown above with two batteries and three resistors. The left
battery has a voltage of n_{1} Volts. If the current through the 2 Ohm
resistor is n_{2} Amps, then
what is the voltage of the right battery? If the voltage of the right battery
is n_{3} Volts, then what is n_{3} ?
