The Difference between Watt and Volt – All You Need to Know

Electricity is a vital aspect of modern life that powers our homes, businesses, and the multitude of electronic devices that we depend on every day. However, with its many technical terms and concepts, it can be challenging to understand the various components that make it all work. Two terms that often cause confusion are watts and volts, even though they are both measurements of electrical power. In this article, we’ll highlight the difference between watts and volts to help clear up any misunderstandings.

What is a Watt?

A watt is the unit of measurement for electrical power, usually used to describe the amount of energy that an appliance or device consumes. This measurement is calculated by multiplying the voltage (measured in volts) and the current (measured in amperes). For example, an appliance that uses one ampere of current at 120 volts uses 120 watts of power (1 x 120 = 120). A higher wattage means more power consumption.

What is a Volt?

A volt is the unit of measurement for electrical voltage, which is the force that pushes electrical current through a circuit. This term is used to describe the electrical potential difference between two points in a circuit, such as the power source and the appliance. In other words, voltage is what gives the electrical current the energy to flow. The higher the voltage, the stronger the force pushing the current, and the higher the electrical energy in the current. For example, most household outlets in the US provide 120 volts of power.

Differences between Watt and Volt

The primary difference between watts and volts is that watts measure power consumption, while volts measure the potential difference that creates the current flow. In simple terms, watts describe how much power an appliance or device consumes, while volts measure the force that powers the current. Also, while voltage affects the strength of the electrical current, it doesn’t necessarily affect the amount of energy consumed by the device.


In summary, watts and volts are both essential measurements in understanding electrical power, but they measure different aspects of it. A watt is the measure of the amount of electrical energy used by an appliance or device, while a volt is the measure of the electrical potential difference that creates the current flow. By understanding the difference between the two, you can better grasp how electricity works and use that knowledge to make informed decisions about energy consumption.
