Calculate Power in Series RL Circuit
A 200 Ω resistor and a 50 Ω XL are placed in series with a voltage source, and the total current flow is 2 amps, as shown in Figure. Figure…
Power Factor
Power factor (pf) is the ratio between true power and apparent power. True power is the power consumed by an AC circuit, and reactive power is the power that is…
Apparent Power, True Power, Reactive Power & Total Power
Apparent Power Apparent power (S) is the power delivered to an electrical circuit. The below Equation is a mathematical representation of apparent power. The measurement of apparent power is in…
Power Triangle
In AC circuits, current and voltage are normally out of phase and, as a result, not all the power produced by the generator can be used to accomplish work. By…
