Understand that power is defined as the rate at which work is done or energy is transferred over time.
Recall the formula for power: \(P = \frac{W}{t}\), where \(P\) is power, \(W\) is work or energy, and \(t\) is time.
Identify the SI units for work or energy, which is the joule (J), and for time, which is the second (s).
Recognize that the unit of power is therefore joules per second, which is given a special name: the watt (W).
Conclude that among the options, the standard SI unit for power is the watt (W), not newton (N), volt (V), or joule (J).
