WebIn a purely resistive circuit, all circuit power is dissipated by the resistor (s). Voltage and current are in phase with each other. In a purely reactive circuit, no circuit power is dissipated by the load (s). Rather, power is alternately absorbed from and returned to the AC source. Voltage and current are 90° out of phase with each other. WebPower is absorbed by the circuit When p(t) is negative: Power is absorbed by the source (transferred from the circuit to the source). This is possible due to the storage elements in the circuit (capacitors, inductors) Average Power: Since instantaneous power changes with time, it is difficult to measure. simply dainty ac llc
