Technician A says voltage will not exist between any two points in a circuit if the potential is zero. Technician B says corrosion is NOT a contributing factor to voltage drop. Who is correct?
A) Technician A only
B) Technician B only
C) Both Technician A and B
D) Neither Technician A nor B

Question

Quizplus · Accepted Answer

Technician A is correct because voltage is the difference in potential between two points in a circuit. If the potential is the same at both points, then there is no voltage between them. Technician B is incorrect because corrosion can indeed contribute to voltage drop, as it increases the resistance of the circuit and thus reduces the amount of voltage that can flow through it.
