Current in a purely inductive circuit lags the voltage by 90 degrees. The apparent power in such a circuit will be zero, because the power factor is zero, however, energy will still be transferred, and VARs (Volt-Amps-Reactive) will be non-zero.
It is phase shifted 90 degrees out of phase with the voltage. This is the result of the inductor "holding" energy, then releasing it. This is then reactive power, not real power, so it cannot be used to do any real work.
Inductors and capacitors are called reactive elements in electric circuits.these reactive elements also offer resistance in the circuit termed as reactance
for inductor it is wL (-j)
for capacitor i is 1/wC (j)
where L,C and w are inductance , capacitance and frequency of the AC source respectively
when clubbed with resistance the the resultant of the resistance and reactance gives us the impedance of a circuit
if the impeadence(R=0) of the circuit is of inductor only then these are called as purely inductive circuits
if the impedence of the circuit is dominated by inductor ( wL > 1/wC ) even though the circuit has resistance and capacitor then these circuits are called inductive circuits
the current lags behind the voltage by 90 deg. phase angle ( if the circuit is pure inductive ,otherwise the angle depends on the value of inductance)
The properties of a series alternating-current L-R-C circuit at resonance are:the only opposition to current flow is resistance of the circuitthe current flowing through the circuit is maximumthe voltage across the resistive component of the circuit is equal to the supply voltagethe individual voltages across the inductive and capacitive components of the circuit are equal, but act in the opposite sense to each otherthe voltage appearing across both the inductive and capacitive components of the circuit is zeroif the resistance is low, then the individual voltages appearing across the inductive and capacitive components of the circuit may be significantly higher than the supply voltage
the current in series will be same..
A voltage error circuit is called an error amplifier and happens when there are discrepancies between the voltage output and the reference voltage. A current error circuit happens when there is a disruption of flow in an ammeter.
In this case current flows from a high voltage to a lower voltage in a circuit.

Inductors tend to oppose a change in current, so the initial current is low, and rises according to the RC time constant of the circuit to a final value.
The PF will increase
the current in series will be same..
Current flows
When you close an inductive circuit, since an inductor resists a change in current, the initial reaction of the load is to look like a high resistance. As current builds, the resistance falls. With a theoretical source and inductor, current would eventually reach infinity, that is after infinite time, but practical sources and inductors will reach a plateau current. When you open an inductive circuit, again, since an inductor resists a change in current, the inductor attempts to maintain that current, but there is no conductivity for that current so, the inductor presents a high voltage spike in the reverse direction it was initially "charged" with. With a theoretical inductor, and theoretical infinite impedance, the voltage spike would be infinite. Again, practical inductors have a maximum voltage spike, but this spike can still be quite high, even thousands of volts, which can damage the circuit, so it is important to maintain a conduction path for the collapsing field, often a diode, or a resistor/capacitor filter.
current remains same in series while divide itself in parallel circuit
When you add resistance to a circuit, current goes down. Ohm's Law: current = voltage divided by resistance.
A voltage error circuit is called an error amplifier and happens when there are discrepancies between the voltage output and the reference voltage. A current error circuit happens when there is a disruption of flow in an ammeter.
When the circuit is interrupted, the current stops flowing.
In a series circuit, if the current is broken the flow of all electricity stops.
If the circuit is closed the electric current will be closed as well.
