Power is measured in ___.

Power is measured in watts, which is a unit that quantifies the rate of energy transfer or conversion. In the context of electrical systems, power is determined by multiplying voltage (measured in volts) by current (measured in amperes). Therefore, the relationship can be shown in the formula: Power (watts) = Voltage (volts) × Current (amperes). This highlights how watts serve as an essential measurement for understanding how much electrical energy is being consumed or generated per second in an electrical circuit.

The other options represent different electrical concepts: volts measure electrical potential, ohms measure resistance in a circuit, and amperes measure the flow of electric current. Each of these plays a crucial role in electrical systems but does not directly quantify power as watts do. Understanding the relationship between these different units helps in grasping the fundamentals of electrical engineering and the functioning of various electrical devices.
