Capacitive load: Compared with the power supply, the load current is one phase ahead of the load voltage, when the load is capacitive load (such as compensation capacitive load).A capacitance-like load in a circuit that causes the current to advance the voltage and reduce the circuit's power factor.Generally, the load with capacitive parameters, that is, in line with the characteristics of voltage hysteresis current load as capacitive load. When charging and discharging, the voltage can not change. Its corresponding power factor is negative. The power factor of the corresponding inductive load is positive.

In the high frequency domain, it refers to the load whose imaginary part is negative.Capacitance-like loads in a circuit can make the load current one phase ahead of the load voltage (compared to the power supply), reducing the circuit power factor.Generally, the load with capacitive parameters, that is, in line with the characteristics of voltage hysteresis current load as capacitive load. When charging and discharging, the voltage can not change. The corresponding power is negative. The power factor of the corresponding inductive load is positive.

General power control products, the given load, if not specified is given is the apparent power; That is, total capacity power; It includes both active power and reactive power; And the general inductive load description is often given in the size of the active power, such as fluorescent lamp, labeled as 15 to 40 watts of fluorescent lamp, ballast power consumption of about 8 watts, in fact, considering the use of timer, induction switch in control of it, it should be added to the 8 watts.
The specific value of the reactive power of the sensitive part of the product can be calculated by its power factor.

The capacitive reactance is larger than the inductive reactance in the hybrid circuit.In general, there is no pure inductive load and pure capacitive load. Because these two loads do no useful work.

Pure inductive or capacitive loads are used only in compensation circuits. And because the vast majority of the load in addition to resistance, most of the inductive load, so most of the compensation will use capacitance to compensate, so, pure capacitive load is used more than pure inductive load. Such as motors, transformers and so on, usually for inductive load. Some fluorescent lamps are capacitive load.
