What formula is used to calculate watts?

The formula used to calculate watts is W = VA, which represents the relationship between power (watts), voltage (volts), and current (amperes). In this equation, power in watts is the product of voltage in volts and current in amperes. This fundamental formula is essential for understanding electrical systems, as it allows for the calculation of power consumption or generation in various devices and setups.

This concept underlines the importance of both voltage and current in electrical circuits, where increasing either one will result in an increase in power, assuming the other variable remains constant. Understanding this formula helps in tasks such as designing electrical systems, troubleshooting issues, and optimizing energy efficiency in production and other applications.
