A 'purely capacitive' circuit is a theoretical, or 'ideal', circuit, in which the resistance and inductance of the circuit is ignored, and in which the load current theoretically leads the supply voltage by exactly 90 electrical degrees. It is often used as a means of introducing students to the behaviour of 'real' a.c. circuit which contain contain resistance and inductance, as well as capacitance.

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.

What is a capacitive 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.


In a purely resistive ac circuit the current and voltage?

Voltage and current will be in phase for a purely resistive load. As a load becomes more inductive or capacitive, the phase angle between voltage and current will increase.


Voltage current relation in passive circuit?

in passive circuit it depends on the type of load 1. if the load is purely resistive the voltage and current will be in phase 2.if the load is purely inductive the current lags the voltage by 90 dgree 3.if the load is purely capacitive the currents leads the voltage by 90 degree


Name type of circuit load which the apparent power is greater than the active power?

these two types of circuit loads are the purely capacitive loads and purely inductive loadsAnother AnswerApparent power will be larger than true, or active, power in ANY circuit, other than a purely-resistive circuit or an R-L-C circuit at resonance.

A circuit with a lagging current means the circuit is?

Inductive. Voltage (E) leads current (I) in an inductive (L) circuit and current (I) leads voltage (E) in a capacitive (C) circuit. (ELI the ICEman)


What is the applied voltage to a resistive capacitive circuit?

this is the amount of voltage a circuit can hold.


In a capacitive AC circuit the current is?

leading the voltage.


When does power consumed in an ac circuit becomes zero?

'Power' is not 'consumed'; it is simply a 'rate' -the rate at which 'energy' is being consumed.No energy is being consumed by a load which is either purely inductive or purely capacitive so, for such loads, the rate of energy consumption, or the power, would be theoretically be zero. However, purely inductive or capacitive circuits only exist in theory, and all circuits exhibit some degree of resistance, so you will never have a condition under which the power of an a.c. circuits truly becomes zero.


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.
