FAQs

What is the power factor for a purely capacitive circuit is always percent? ›

In a purely capacitive circuit, the current leads the voltage by 90° and the power factor is zero leading.

When viewing the sine wave of a purely capacitive circuit, which of the following lags the current? ›

Looking at the graph, the current wave seems to have a “head start” on the voltage wave; the current “leads” the voltage, and the voltage “lags” behind the current. Voltage lags current by 90° in a pure capacitive circuit.

What does the power factor represent? ›

Power factor is an expression of energy efficiency. It is usually expressed as a percentage—and the lower the percentage, the less efficient power usage is. Power factor (PF) is the ratio of working power, measured in kilowatts (kW), to apparent power, measured in kilovolt amperes (kVA).

What is the power factor of a purely inductive circuit quizlet? ›

The true power used or consumed in a purely inductive circuit is zero watts.

What is the formula for power factor? ›

PF = kW / kVA

A steel stamping operation runs at 100 kW (Working Power) and the Apparent Power meter records 125 kVA. To find the PF, divide 100 kW by 125 kVA to yield a PF of 80%. This means that only 80% of the incoming current does useful work and 20% is wasted through heating up the conductors.

What is the value of the power factor of a purely resistive AC circuit? ›

Therefore, since the voltage and current are in phase for a purely resistive circuit, its PF is 1.

What is the formula for capacitance in AC circuit? ›

The property of a capacitor to store a charge on its plates is called its capacitance, (C). Thus a capacitors charging current can be defined as: i = CdV/dt. Once the capacitor is “fully-charged” the capacitor blocks the flow of any more electrons onto its plates as they have become saturated.

What is the power factor of a purely resistive load in a three-phase AC circuit? ›

For the purely resistive circuit, the power factor is 1 (perfect), because the reactive power equals zero. Here, the power triangle would look like a horizontal line, because the opposite (reactive power) side would have zero length.

What is the formula for the AC voltage applied to a capacitor? ›

Capacitors are devices that collect and store electrical charges on their plates. We have also seen that a capacitor is linked to an AC power source. v = vm sin(t) is the equation for voltage from the voltage source.

What happens if I connect A capacitor to A generator load? ›

If such load is connected, the capacitive current causes over voltage, and may damage the generator beyond a certain value.

Which type of wattmeter is used for power measurement? ›

Induction wattmeter

Induction wattmeters are used to measure the number of watts of electricity flowing in a circuit or wire. They are used in electric power generation, electric power distribution, and electric power transmission systems to measure power and energy.

How to find power factor in AC circuit? ›

The power factor is the cosine of the phase difference between voltage and current, and as a result, the power factor is measured using the formula Power Factor = cosɸ, where ɸ is the phase difference between the voltage and current phasor.

What is the power factor of an AC circuit containing pure inductor? ›

In pure Inductor, power factor will always be zero.

What is the power factor of a pure resistive circuit a pure inductive circuit and a pure capacitive circuit? ›

Hint: The power factor is $1$ (perfect) for the purely resistive circuit because the reactive power approaches zero. For the completely inductive circuit, the power factor is zero because true power approaches zero. A similar could be stated for a purely capacitive circuit.

What is the value of power factor in pure inductive and capacitive AC circuit? ›

Therefore, the power factor of pure inductor and pure capacitor circuit is zero.

What is the power factor of a capacitive circuit? ›

Therefore, the power factor of pure inductor and pure capacitor circuit is zero.

What is the power in a purely capacitive circuit? ›

Assertion (A) : In purely capacitive AC circuit, average power consumed is zero. Reason (R) : The phase difference between the current and voltage in case of a purely capacitive circuit is 90∘.

What is the percentage of power factor? ›

Power factor is a ratio of true power to apparent power. There exist good, bad, and poor power factors with specific ranges where 1.0 to 0.95 is said to be good, 0.95 to 0.85 poor, and 0.85 and below is said to be bad. When the system achieves a power factor of 1.0, the system is approved to be perfect.

Does a capacitive load always have a power factor? ›

A capacitive load always has a leading power factor.
