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.
Why is capacitive voltage higher than inductive voltage in an R-L-C circuit?
It isn't necessarily so. The capacitive voltage is the product of the current and capacitive reactance, while the inductive voltage is the product of the current and the inductive reactance. So it depends whether the capacitive reactance is greater or smaller than the inductive reactance!
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.
A capacitive device in a single phase ac circuit causes the current waves to?
Lead the voltage waves
In RC circuits the voltage leads the current?
Inductive. Used to remember this by "Eli" the "ice" man. "(e) Voltage (l) (Inductive circuit) (i) current", the ,"(i) Current (c) (capacitive circuit) (e) voltage, man.
In a capacitive AC circuit the current is?
leading the voltage.
What happens to current flow in a capacitive circuit in comparison to voltage?
The current leads the voltage by 90degree....

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 series RLC circuit at frequencies above resonance is the circuit capacitive or inductive?
in series you XL, voltage leads the current, and in Parallel current leads the voltage. so your answer should reflect on this theory.
A capacitive device in a single phase ac circuit causes the current waves to?
Lead the voltage waves
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.
What is purely capacitive circuit means?
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.
