What happens to reactive power in a circuit that has both inductance and capacitance?
Inductors are considered to be a load for reactive power, meaning that they will draw reactive power from the system. Capacitors are considered to be sourced of reactive power, they feed reactive power into the system. If you have a circuit that is at unity (balanced with inductors and capacitors) no reactive power will be drawn from the source. You will have unity power factor. If your circuit is more inductive than capacitive it will be drawing reactive power from the source. The opposite is also true for capacitors.
What is it mean to say that an alternating current leads or lags an alternating emf?
It is another way of saying that the circuit is capacitive reactive circuit. Look up the mnemonic ELI the ICE man. ELI, voltage leads the current in an inductive circuit. ICE, current leads the voltage in a capacitive circuit.
Which excitation synchronous motor drawn reactive power?
Hi, Under excitation - inductive reactive power Over excitation - Capacitive reactive power.
How many degrees are the current and voltage out of phase in a pure capacitive circuit?
In a pure (ideal) capacitive circuit, current leads voltage by 90 degrees.
What terminology describes the effect of a reactive load in a circuit and the change of the voltage-current timing relationship?
The terminology that describes the effect of a reactive load in a circuit is "phase shift." In circuits with reactive components like inductors and capacitors, the voltage and current do not peak at the same time; instead, they are out of phase. This results in a timing relationship where the current either leads or lags the voltage, depending on whether the load is inductive or capacitive, respectively. This phase difference can affect the overall power factor of the circuit.
What is a reactive circuit?
A circuit that has only a capacitor in it. Or the net reactance is below zero, making it capacitive. The current leads the voltage in a negative (capacitive) reactive circuit.
What is a condition for resonance for an electrica circuit with reactive element?
For resonance to occur in an electrical circuit with a reactive element, the reactive element's reactance needs to be equal and opposite to the circuit's impedance. This occurs when the capacitive and inductive reactances cancel out, resulting in a net impedance that is purely resistive. At this point, maximum current flows through the circuit, enhancing certain frequencies.
When voltage and current in a circuit do not reach their maximum amplitude and zero level simutaneously?
This means there is a reactive component, either inductive or capacitive, to the load.

What is the relationship between the current and the components in a purely capacitive circuit?
In a purely capacitive circuit, the current and the components have a relationship where the current leads the voltage by 90 degrees. This means that the current and voltage are out of phase in a purely capacitive circuit.
Why the output voltage of transformer increases when capacitive loading is used?
if the load is capacitance then reactive power is injected in the circuit, as we know that reactive power is directly proportional to the voltage, if there is increase in reactive power automatically voltage at load end of the tranformer is increases
What is the applied voltage to a resistive capacitive circuit?
this is the amount of voltage a circuit can hold.
Which excitation synchronous motor drawn reactive power?
Hi, Under excitation - inductive reactive power Over excitation - Capacitive reactive power.
In a capacitive AC circuit the current is?
leading the voltage.
Is it really possible to avoid reactive power in electrical circuit?
yesAnswerNo, but you can counter its effects. For example, if your load is inductive, then you can counter the effects of its inductive reactance by introducing capacitors with equal capacitive reactance.
How many degrees are the current and voltage out of phase in a pure capacitive circuit?
In a pure (ideal) capacitive circuit, current leads voltage by 90 degrees.
