# Reactive power

Reactive power is the power that is required to maintain the current in an inductive circuit. The current in an inductive circuit lags the voltage by 90 degrees. This means that the reactive power must be supplied to the circuit to keep the current flowing. Reactive power is measured in volt-amperes reactive (VARs).

### What is active & reactive power?

Active power is the power that is consumed by an appliance or device. It is measured in watts and is the product of the voltage and current.

Reactive power is the power that is required to maintain the magnetic field in an appliance or device. It is measured in volt-amperes reactive (VAR) and is the product of the voltage and the current.

#### What is an example of reactive power?

Reactive power is a measure of the power that is being wasted in an electrical system. It is the product of the current and the voltage, and is measured in watts. Reactive power is caused by the inductance and capacitance of the system, and is wasted when the system is not operating at its optimal efficiency.

#### What is reactive power and its formula?

Reactive power is a type of electrical power that is measured in units of volt-amperes reactive (VAR). It is the product of the voltage and amperage of an AC circuit multiplied by the sine of the phase angle between the voltage and current. The formula for reactive power is:

P = VI sinθ

Where:

P = reactive power (in VAR)

V = voltage (in volts)

I = current (in amperes)

θ = phase angle (in degrees)

Reactive power is required to maintain the current in an inductive circuit, such as a transformer or an inductor. It is also used to create a magnetic field in electromagnets. Who generates reactive power? In an electrical power system, reactive power is generated when the system's load requires it. The reactive power is generated by the system's generators and is consumed by the system's loads. Is reactive power negative or positive? Reactive power is the power that is stored in an electrical circuit and then released back into the circuit. It is measured in watts and is a unit of power. Reactive power is either positive or negative, depending on the direction in which it is flowing. If the reactive power is flowing into the circuit, it is considered to be positive. If the reactive power is flowing out of the circuit, it is considered to be negative.
