9.6: Electrical Energy and Power

E = ∫ Pdt (9.6.12) (9.6.12) E = ∫ P d t. is the energy used by a device using power P for a time interval t. If power is delivered at a constant rate, then then the energy can be found by E = Pt E = P t. For example, the more light bulbs burning, the greater P used; the longer they are on, the greater t is.

Electrical Energy, Power and Charge

Electrical 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 equals Power multiplied by Time, (V*I*t joules). So electrical energy (the work done) is obtained by multiplying power by the time in seconds that the charge (in the ...
