leading the 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.
The capacitive reactance is approximately 4 kΩ .
It's the amount by which voltage leads current (or vice versa) in the AC circuit. By convention, the phase angle is positive in inductive circuits (where voltage leads current) and negative in capacitive circuits (where current leads voltage).AnswerUnfortunately, the original answer has things the wrong way around. By definition, phase angle is the angle by which the current leads or lags the supply voltage (not the other way around). Therefore, the phase angle is considered negative (current lagging) for an inductive circuit, and positive (current leading) for a capacitive circuit. This is because, for a phasor diagram, counterclockwise is the positive direction, whereas counterclockwise the the negative direction.
Because the only opposition to current flow is the resistance of the circuit. This is because, at resonance, the vector sum of the inductive and capacitive reactances is zero.
Impedance in an AC circuit is like resistance. In fact, impedance is measured in ohms, just like resistance. Impedance takes into account the fact that current and voltage are often not in phase with each other due to capacitive and inductive reactance.
Lead the voltage waves
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 pure (ideal) capacitive circuit, current leads voltage by 90 degrees.

Resistance, capacitive reactance, inductive reactance. Note: None of this is really a "force" - not in the meaning of "force" as used in physics.
The current leads the voltage by 90degree....
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)
If the current rises and falls with the voltage, then the two are said to be 'in phase'; this occurs in a purely-resistive circuit. For inductive or capacitive circuits, the current either lags or leads the voltage.
Assuming you are talking about an AC circuit, then the total opposition to the flow of current in an R-C circuit is called its impedance (symbol: Z), measured in ohms. This is the vector sum of the circuit's resistance (R) and its capacitive reactance (XC) -each also measured in ohms.
The current in any AC circuit reverses every cycle.
