Applying Kirchhoff’s Junction Rule, what happens to the power source and current when the parallel circuit has two branches, each with a resistor, R? In one to two sentences, answer the question and explain your reasoning.

When a parallel circuit has two branches both with a resistor, the power source and current _______ _______________________________________.
This is because __________________________ ______________________________________

Answer 1

When a parallel circuit has two branches both with a resistor, the power source will provide the total current necessary for both branches to have the same voltage. This is because in a parallel circuit, the current flowing through each branch is determined by the resistance of the branch, not the power source.
