The current (measured in amperes) in a circuit is
A) the total number of electrons in the circuit.
B) the amount of the total energy carried by 1 Coulomb of charge.
C) the amount of charge (measured in Coulombs) that passes a point (in the circuit) in 1 second.
D) never lethal if the current is due to positive charges.

Question

Quizplus · Accepted Answer

The current in a circuit is the amount of charge (measured in Coulombs) that passes a point in the circuit in 1 second. Option A is incorrect as the current does not depend on the total number of electrons present in the circuit but on the number of electrons passing through a point in the circuit in a given time. Option B is incorrect as the amount of energy carried by 1 Coulomb of charge is called voltage, not current. Option D is incorrect as lethal current can occur whether the current is due to positive or negative charges.
