What’s the Difference Between Amps, Volts and Watts?

May 04, 2023

If you’ve ever used an electronic device, then you’ve probably heard the terms “volts”, “amps” and “watts” thrown around at some point or another. Although many of us are somewhat familiar with their usage, most people do not fully understand the differences between the three. These terms are very important whenever it comes to measuring electricity. By thinking about them in plumbing terms, it is possible to gain a better understanding that can help you whenever you are trying to make some of the electrical decisions in your home.


Think of amps like the flow of water from your faucet. Whenever you turn on a faucet in your home, water flows out of the faucet and into your sink. Whenever you flip a switch, electricity will flow from your outlet into the device. This flow is measured in amps.


Volts are best compared to water pressure. Whenever you turn your water faucet on to get the flow (amps), you rely on an existing pressure to allow that water to flow quickly and freely from the faucet. Voltage works as the electrical pressure in your electrical system. This ensures that you will always have the potential electrical flow that you need whenever you flip the switch.


Whenever you turn your water on, the total amount that you consume is typically measured in gallons or liters. This is the usage that you are charged for on your water bill. To similarly gauge the amount that your electrical company charges you for, you use Watts. Watts are determined by multiplying the electrical pressure (Volts) by the total flow (Amps) in order to determine your total power consumption in Watts.

Now that you know what these terms represent, you can better understand the ratings on each of your devices. This can also help to demystify your electric bill so that everything is that much clearer. If you have any questions about your electrical system, don’t hesitate to call your electrician in the Las Vegas and Salt Lake City areas, Yes!.
