Question: 1 / 400

Which of the following defines the flow of electric charge in a circuit?

Voltage

Current

The flow of electric charge in a circuit is defined as current. Current is measured in amperes (A) and represents the rate at which electric charge flows past a point in a circuit. It can be visualized as the movement of electrons through a conductive path.

In a circuit, current is directly affected by voltage, which is the electric potential difference that drives the flow of charge. While voltage determines the force that pushes the charges, it is the current that actually represents the movement of those charges.

Power relates to the amount of energy consumed or transferred per unit of time, and resistance is the opposition to the flow of current in a circuit. Both are important concepts in understanding how circuits work, but they do not define the actual flow of electric charge like current does.
