Three resistors are connected side by side across the same cell. Which quantity is the same across every one of them?
AThe current through them
BThe power used by them
CThe voltage across them
DThe charge stored in them
Answer & Solution
Correct answer: C. The voltage across them
1. Resistors connected side by side across one cell form a parallel circuit.
2. There are only two sets of electrically common points in a parallel circuit.
3. The voltage is therefore equal across all components in the circuit.
4. The currents through the separate branches add up to the total current, so they are generally different from one another.
