A)positive, positive
B)positive, negative
C)negative, positive
D)negative, negative

Question

Quizplus · Accepted Answer

Electrons are negatively charged particles that flow from the negative terminal of the voltage source, through the circuit, to the positive terminal of the voltage source. Therefore, the side of the resistor where current enters (i.e. the negative side) will have a negative polarity, while the side of the resistor where current exits (i.e. the positive side) will have a positive polarity. Choice C is the only option that reflects this correctly.
