Question

Of the different power values in an rl circuit, which one is known as quadrature power?

1) Real power
2) Reactive power
3) Apparent power
4) Complex power

Answer 1

In an RL circuit, the quadrature power is known as reactive power, represented by the symbol 'Q'. Reactive power is associated with the energy stored in the circuit's inductance or capacitance and does not perform any actual work.

Step-by-step explanation:

In an RL circuit, the quadrature power is known as reactive power. Reactive power is the portion of electricity that oscillates between the source and load, associated with the energy storage in the circuit's inductance or capacitance. It is measured in var (volt-ampere reactive) and is denoted by the symbol 'Q'.

The real power, also known as active power, is the power consumed by the circuit and converted into work and heat. It is represented by the symbol 'P'. Apparent power is a combination of real power and reactive power and is represented by the symbol 'S'. Complex power is a conceptual representation of the total power in a circuit, expressed as the sum of real power and reactive power mathematically combined as a complex number.

When discussing power in the context of an RLC circuit, the average power (Pave), reactive power ('Q'), and apparent power ('S') are directly influenced by the phase angle between the voltage and the current, which can vary with frequency. In such circuits, both voltage and current are not necessarily in phase, leading to the concept of power factor, which can range from -1 to 1 and reflects the ratio of real power to apparent power.
