Hello fellows, I hope you all are doing great. In today’s tutorial, we will have a look at **Difference Between Leading and Lagging Power Factor**. In AC power system the 2 most important parameters which are related to the power factor are lagging and leading power factors. the leading power factor current leads the voltage. While for lagging power factor current lags the applied voltage. The circuit that has leading and lagging power factor depend on the load connected.

Before discuss lagging and leading power factor we must know about power factor. It is very important parameter of an electrical power system. It is a dimensionless quantity It is expalinaniton of enrgy. Its value lies in form of percentage if percentage is less P.F is less.Its is ratio of operating powr to apparent power. Apparent powr called power demand for laod. It is multiple of volts and ampere its units is KVA

In the case of direct current circuitry, we can get the power of any circuitry through the multiple of voltmeter and ammeter reading. .It exits in both single and 3 phase circuits.But for ac circuitry products of these two parameters give only apparent power not the actual powerIt has no dimensions. Its value lies between plus minus and positive minusHence in ac circuitry, the net power given to circuitry which is apparent power is not only used through the circuitry. The power used by the circuit is called actual power in simple words **power factor **is the cosine of phase difference among voltage current. Its formula is power factor=Actual power/Apparent power. In today’s post, we will have a detailed look at the comparison among lagging and leading power factor and find their differences. So let’s get started with *Difference Between Leading and Lagging Power Factor.*

#### Difference Between Leading and Lagging Power Factor

**Leading Power Factor**

- For this power factor current flowing through the load lead the voltage given to the load.

- Leading power factors is exits for the capacitive load connected with the circuitry.
- If the leading power factor to be corrected of the system then connected the inductive load in the system.
- The value of leading power factor lies between -1 to zero.
- Its reactive component is negative.
- The load which has leading power factors are capacitive load

motors, capacitor, radio circuitry.

**Lagging Power Factor**

- In lagging power factor load current lags the applied voltage.
- The inductive load connected with the circuitry has lagging power factor.
- Examples of lagging power factor are inductive load like induction motor, generator, relays, etc.
- The correction of lagging power can be done with the use of capacitive load.
- Its value is between zero and one.

- Its reactive element is positive.

That is detailed post about difference between leading and lagging power factor. If you have any query ask in comments. Thanks for reading. Have a good day.
