![]() Understanding Amps, Volts, and Watts helps you use your appliances safely and even save money on electricity bills. This means the hairdryer uses 1200 watts of power to blow hot air. If it works at 120 volts and uses 10 amps, you can find its power: So, if something uses a lot of watts, it's using more electrical power.Įxample: Think of a hairdryer. In our hose example, watts tell us how much water comes out. Watts are how we measure electrical power. Now, let's mix Amps and Volts to make Watts. When you plug in your phone charger, it uses 120 volts to send electricity into your phone. In electricity, higher volts push the current harder.Įxample: In the U.S., most outlets have 120 volts. But if you press hard, the water comes out strong. If you press lightly, the water barely comes out. Imagine it as how hard you press the hose trigger to make water flow. Now, volts are like the "push" behind electricity. More amps mean a stronger flow, like when you turn on a garden hose, and water gushes out fast.Įxample: If a device uses 5 amps, it's like saying it lets 5 units of electrical water flow through it. ![]() Think of electricity like water flowing through a hose. Device or SystemWhat are Amps, Volts and Watts? Amps - The Flow of Electricity ![]() Here is a general guide on appliances and their average wattage usage. Knowing how many watts is also important if solar panels are being installed to see how many and which ones should be used to power the home. When wanting to become more energy efficient it is recommended that appliances which need fewer wattages are preferred. The electrical bill is often calculated by how many watts or energy was consumed.Īppliances which are rated show how much energy the applicant will need to function correctly. Watts measures how much energy is used and with appliances shows how much energy they will consume. Knowing about wattage will help with choosing appliances which will use less energy and save more money. Also, some calculators might have appliance and device types to allow the process to be easier. Entering the figures often creates an accurate result but it should not always be completely trusted. Such as 2 amps by 150 volts, or 2A x 150V, will result in 300 watts, or 300W.Īnother method is to find a reliable wattage calculator online which will do the calculations automatically. Multiplying the amps and the volts together will create the result of how many watts are being generated. The amps are how much power is being consumed where the volts is measuring the pressure of the electrical current. To calculate how many watts a device or system has, knowing the amps and volts is needed. If the wattage is higher this means that there is more electrical energy and power being produced. The amount of voltage and current within the system will determine how many watts are made. It will measure the amount of energy released within a system per second. It may seem overwhelming, but you don’t need an engineering degree to understand what. A fourth being resistance which is measured in ohms. Amps, volts, and watts are three basic concepts you will repeatedly deal with when working on any electrical system. Watts are described as the base unit of the electrical power within electrical systems. 7 thoughts on Amps, Volts, Watts: Differences Explained In Simple Terms. I would have no hesitation in recommending The Local Electrician on the basis that they are very professional, highly skilled, well organised, reliable, responsive, polite and importantly, customer focussed. Everything seemed to go smoothly and I am very satisfied with the work done. Ben in particular made what seemed to me to be a complex job look rather easy. the guys arrived on time and after an on site briefing by Nick, Ben and Hoss got stuck in and completed the jobs with a minimum of fuss. We arranged a date and time for the work to be completed. I checked out the business through various sources and was happy to accept the quote in the knowledge that I would get a high quality job done by a reputable company for a reasonable cost. he provided me with a detailed quote and was able to answer all of my questions and offer suggestions as to the best options to get the desired outcomes. He was polite and friendly and I was immediately impressed by his knowledge and understanding of what I wanted done. It wasn't long until I was contacted by Nick who arrived as planned the following morning. I contacted The Local Electrician in relation to replacing an asbestos meter board and some other general electrical work.
