Linear time-invariant circuits (referred to simply as linear circuits for the rest of this article), for example, circuits consisting of combinations of resistors, inductors and capacitors have a sinusoidal response to the sinusoidal line voltage. A linear load does not change the shape of the input waveform but may change the relative timing (phase) between voltage and current, due to its ind… Webpower vector is theta. The cosine of angle theta is equal to the power factor, as identified in equation 3. Often, electrical equipment manufacturers will identify the power factor by cos (theta), rather than PF. Thus, when an inverter is operating loadswith power factors less than 1, the inverter capacity is effectively reduced. how to earn in bitly
