Electrical power is best described as
the flow rate of electrons in a circuit
the “push” or “pressure” that encourages electrons to flow in a circuit
the rate at which electrical energy is transferred, converted, or consumed
the "push-back" or "friction" that electrons experience as they flow through a circuit
