In a circuit diagram, is the voltage the same at every point along a single connecting wire?
ANo, voltage always decreases gradually along any wire
BNo, voltage only matches at the two endpoints of the wire
CYes, the voltage is the same at every point in a given wire
DIt depends on how long the wire is drawn
Answer & Solution
Correct answer: C. Yes, the voltage is the same at every point in a given wire
1. Wires in circuit diagrams are treated as perfect conductors with no resistance.
2. With no resistance, there is no voltage drop along the wire itself.
3. This means the voltage is the same at every point in a given wire.
