What is Watt?
Watts is a measurement unit used in an electrical system to measure power. It represents the rate at which energy is transferred or consumed per second. It is named to honor James Watt, the inventor of the steam engine. Watts is an important concept for managing, designing, and troubleshooting of the electrical system. By understanding the amount of power consumed by an electrical system, we can determine its efficiency and its impact on the environment.
Watt is also important to determine the cost of energy consumed by a machine. Electricity companies charged customers based on the number of kilowatt-hours(kWh) of energy consumed. One kilowatt-hour is equal to 1000 watts used for one hour.
Watts Formula:
Watts = Volts x Amperes
This formula also known as Power law and can be derived by Ohm’s Law.
Volts are the measure of the electrical potential difference between two places in electrical circuit.
Amperes measure the flow to electric charge through a circuit.
Example: A 60W light bulb consumes 60 watts of power, which is equivalent to 120 volts multiplied by 0.5 amperes. Conversely, a device that consumes or produces more watts will require more voltage or amperes to function properly.
Difference Between Watts And Volts
Unit of measurement for electrical potential difference or voltage Watts and volts are the two different units of measurement that are commonly used in physics in the electricity field. Watts and Volts both are necessary for understanding the working of electric circuits and electric devices. Watts is the unit of power, while volts are the unit of electrical potential difference between two places in the circuit. Watt helps in understanding the quantity of energy being generated or consumed whereas volt helps in understanding the difference in the electrical potential of two places.
