reactive load current Explanation: I added reactive to distinguish the resistive load current (for which the power factor is always positive = power flows to the load) from the reactive load current (which has capacitive and inductive components), in which the power factor can be negative, so that power flows back to the circuit. cccccccccccccccccc Electrical circuits containing dominantly resistive loads (incandescent lamps, heating elements) have a power factor of almost 1.0, but circuits containing inductive or capacitive loads (electric motors, solenoid valves, transformers, fluorescent lamp ballasts, and others) can have a power factor well below 1. If a purely resistive load is connected to a power supply, current and voltage will change polarity in step, the power factor will be unity (1), and the electrical energy flows in a single direction across the network in each cycle. Inductive loads such as transformers and motors (any type of wound coil) consume reactive power with current waveform lagging the voltage. Capacitive loads such as capacitor banks or buried cable generate reactive power with current phase leading the voltage. Both types of loads will absorb energy during part of the AC cycle, which is stored in the device's magnetic or electric field, only to return this energy back to the source during the rest of the cycle. https://upload.wikimedia.org/wikipedia/commons/thumb/b/b9/Po... https://en.wikipedia.org/wiki/Power_factor |

load current Explanation: Po prostu w istniejącym ogólnym kontekście. Odpowiedź MacroJanusa dotyczy tylko jednego składnika prądu obciążenia, na dodatek w obwodzie prądu przemiennego, a nie stałego, patrz http://www.allaboutcircuits.com/textbook/alternating-current... |
