Inductive current refers to the flow of electric current that occurs due to the presence of inductance in a circuit. This inductance arises from the magnetic field generated around a conductor when current flows through it. Inductive currents can cause phase shifts in alternating current circuits and require additional considerations for proper circuit design and operation.

What is the relationship between voltage and current in an inductive circuit?
In an inductive circuit, the current lags behind the voltage due to the energy stored in the inductor's magnetic field. The voltage leads the current by 90 degrees in an ideal inductive circuit. The relationship between voltage and current is described by the equation V = L di/dt, where V is voltage, L is inductance, di is change in current, and dt is change in time.
How do you calculate inductive time constant?
The inductive time constant (L/R) is calculated by dividing the inductance of the inductor (L) by the resistance of the circuit (R). It represents the time it takes for the current in the circuit to reach approximately 63.2% of its maximum value during the charging or discharging of the inductor.
Is inductive reactance directly or inversely proportional to frequency?
Inductive reactance is directly proportional to frequency. This means that as the frequency of an AC circuit increases, the inductive reactance also increases. Conversely, as the frequency decreases, the inductive reactance decreases.
What is difference in resistance and reactance?
Resistance is the opposition to the flow of current in a circuit, measured in ohms, while reactance is the opposition to the change in current or voltage in a circuit, mainly due to inductance or capacitance. Resistance causes energy loss in the form of heat, while reactance causes a phase shift in the alternating current waveform.
What are the three types of opposition to current flow that impedance represents?
Impedance represents three types of opposition to current flow: resistance that dissipates energy as heat, capacitance that opposes changes in voltage, and inductance that opposes changes in current by storing energy in a magnetic field.

What are the properties of inductive load?
inductive load does not allow the current to become zero eve though the supply source get removed . inductive load reduce the power factor . they does not allow sudden change in current in the load ...
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)
How do you determine the starting current of inductive load?

explain what current grows gradually when an inductive circuit is switched on?
The AC current grows gradually when an inductive circuit is switched on. This specific current, also know as a electromagnetic field, is slowly growing, then shrinking, and changing, because of the wire current.
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!
Do air conditioners use resistive load or inductive load?
resistive loadAnswerIf the current is driving a motor, then the load is resistive-inductive.
When a series circuit containing resistance and inductive reactance is connected to a ac supply the current will?
The load current will lag the supply voltage by an angle called a 'phase angle', determined by the values of resistance and inductive reactance. The magnitude of the load current will be determined by the impedance of the circuit, which is the vector sum of the resistance and inductive reactance.
Why is there no inductive reactance in DC circuits?
Inductive reactance is a resistance by inductors to the change of current flow, and is dependent on the frequency at which the current oscillates. DC current flows in only one direction so an inductor's impedance remains the same.
What is phase between voltage and current in a pure inductive circuit?
The phase angle between voltage and current in a purely inductive circuit, under ideal circumstances where there is no resistance at all, is 90 degrees.
What is the relationship between voltage and current in an inductive circuit?
In an inductive circuit, the current lags behind the voltage due to the energy stored in the inductor's magnetic field. The voltage leads the current by 90 degrees in an ideal inductive circuit. The relationship between voltage and current is described by the equation V = L di/dt, where V is voltage, L is inductance, di is change in current, and dt is change in time.
What is the effect of inductive load on a single phase full wave bridge rectifier?
rectifier is used to resist the current likewise in bridge wave rectifier ,the inductive load is used to resist high amount of current because in bridge wave we cannot resist the current by using rectifier ..so we are using inductive load here
