Calculate Power Given Voltage And Current

Calculate Power Given Voltage And Current. Power= current^2 x resistance or. For example, my laptop charger has 1.2 a max current draw but it works with voltages from 100 v to 240 v (all rms).

RMS Voltage Calculator from circuitdigest.com

But we have designed this one especially for dc circuits (as well as work for single phase ac circuits without power factor. Real power when rms voltage and current is given is the average power in watts delivered to a load. It is the actual power dissipated by the load and is represented as p = irms * vrms * cos (ϑ) or real_power = root mean square current * root mean square voltage * cos (theta).
