When asked to find the magnitude and direction of all branch currents using the superposition theorem, our first step is to eliminate all but one of the batteries by replacing them with a ____.
A)resistor
B)short circuit
C)direct circuit
D)larger power source

When using the superposition theorem, we eliminate one source at a time and replace it with a short circuit. This is because a short circuit will effectively remove the influence of that source while still allowing current to flow through the circuit. Replacing a battery with a resistor, direct circuit, or larger power source would not achieve the same effect.
