WebV (V) = E (J) / Q (C), which means that the voltage in volts is calculated by dividing the energy in joules by the charge in coulombs. It can also be expressed as Volt = joule / coulomb or V = J / C For example, If the energy consumption of an electrical circuit is 90 joules with a flow charge of 7 coulombs, what will be the voltage supply?

WebIn doing so it uses 240,000 joules of energy. What was the power used, i.e. how many watts (W) were used? The time taken was 1 x 60s + 46s = 106 seconds. We can now simply enter the number of joules (240,000) and the number of seconds (106) into the calculator and click Calculate to show that the kettle used just over 2264 watts. WebFeb 7, 2024 · These are approximate amps ratings, so they’re pretty close to what you’d measure with a Kill-A-Watt meter or test meter, for example. As you can see, a typical higher-power 1,700W air fryer uses a bit over 15 amps while a smaller unit uses about 9 amps. How an air fryer works Web100A to watts calculation with voltage of 230V AC. For AC power supply, watts are equal to the power factor times amps times volts. watts = PF × amps × volts. For resistive load … bird flu cases worldwide
