Watts vs. Volts: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Updated on October 22, 2023
Watts measure power or the rate of energy transfer, while volts measure electric potential difference between two points.

Key Differences

Watts and volts are essential terms in the realm of electricity and electronics. Watts, named after James Watt, denote the unit of power, signifying how fast energy is used or produced. In contrast, volts, named after Alessandro Volta, represent the unit of electric potential difference between two points in a circuit.

When discussing the relationship between watts and volts, it's pivotal to understand that power (watts) is the product of voltage (volts) and current (amperes). Hence, a device's power rating, in watts, reveals how swiftly it consumes energy, whereas its voltage rating, in volts, indicates the potential difference required for its operation.

Both watts and volts have significant implications in daily life. For instance, light bulbs are often labeled with watts, highlighting their energy consumption rate. Simultaneously, household electrical outlets in the U.S. typically provide 120 volts, determining the kind of appliances compatible with them.
