What does the watt (W) measure in terms of electricity?

Amount of an electric current
Electric energy being used in 1 second
Pressure or force that pushes the flow of electrons forward
Resistance of an electric current

The correct answer is: Electric energy being used in 1 second

The watt (W) measures the rate at which electric energy is being used in 1 second. It is a unit of power that shows how quickly energy is being transformed or used. The other options are not correct because: A. Amount of an electric current: This is measured in amperes (A), not in watts. C. Pressure or force that pushes the flow of electrons forward: This describes voltage, which is measured in volts (V). D. Resistance of an electric current: This is measured in ohms (Ω), not in watts.
