WebElectrical Power. 1 watt (W) = 1 joule/second (J/s) So if 1 watt = 1 joule per second, it therefore follows that: 1 Joule of energy = 1 watt over one unit of time, that is: Work … WebPower is the rate of using or supplying energy: Power =. Energy. Time. Power is measured in watts (W) Energy is measured in joules (J) Time is measured in seconds (s) Electronics is mostly concerned with small quantities of power, so the power is often measured in milliwatts (mW), 1mW = 0.001W. For example an LED uses about 40mW and a bleeper ...
