Question

4.1.2 quiz: electricity
question 4 of 10
which statement describes the path of electrons from a battery to a circuit?
a. electrons move through the battery from the positive terminal to the negative terminal and then into the circuit.
b. electrons move away from the positive end of a battery and then through the circuit toward the negative end of the battery.
c. electrons move away from the negative end of a battery and then through the circuit toward the positive end of the battery.
d. electrons move through the battery from the negative terminal to the positive terminal and then into the circuit.

Explanation:

Electrons are negatively charged. In a circuit, they move from the negative terminal (where there is an excess of electrons) through the circuit to the positive terminal (which has a deficiency of electrons). Option C correctly describes this movement. Option A has the wrong direction within the battery. Option B has the wrong starting and ending points. Option D has the wrong direction within the battery.

Answer:

C. Electrons move away from the negative end of a battery and then through the circuit toward the positive end of the battery.
