What term describes the flow of electric charge in a circuit?

  1. Voltage

  2. Current

  3. Resistance

  4. Power

The correct answer is: Current

The term that describes the flow of electric charge in a circuit is current. Current specifically refers to the rate at which electric charge flows through a conductor, such as a wire, defined in units called amperes (A). It is a fundamental concept in electrical engineering and is crucial for understanding how circuits operate. Voltage represents the potential difference that drives the flow of current, but it does not measure the flow itself. Resistance, on the other hand, is a measure of how much a material opposes the flow of current, influencing how much current will flow for a given voltage. Power is the product of voltage and current, representing the rate at which energy is transferred or converted. Therefore, while all these terms are related to electrical circuits, current specifically denotes the flow of electric charge.
