What is the impedance of a pure inductance?

So whenever a sinusoidal voltage is applied to an inductive coil, the back emf opposes the rise and fall of the current flowing through the coil and in a purely inductive coil which has zero resistance or losses, this impedance (which can be a complex number) is equal to its inductive reactance.

What is the nature of current in pure inductance?

With pure inductive or pure capacitive circuits, the current is 90o out of phase with the circuit voltage; thus, the cos φ = 90o.

Does a pure inductor have resistance?

A perfect inductor has no resistance. DC current flows through it with no voltage drop. The correct term is “inductive reactance.” Like resistance, reactance is measured in Ohms. And like resistance it is a measure of the relationship between current and voltage in an electrical component.

Why it is not possible to make a pure inductor Why?

An ideal inductor or a pure inductor is defined as an inductor which has zero or no internal resistance within its coil. But this is possible only theoretically, because in real life a lot of energy is lost due to heating of the coil from its own internal resistance.

What is pure inductance load?

The circuit which contains only inductance (L) and not any other quantities like resistance and capacitance in the circuit is called a Pure inductive circuit. In this type of circuit, the current lags behind the voltage by an angle of 90 degrees.

What is the active power in pure capacitive circuit?

The active power drawn by a pure inductive and a pure capacitive circuit is zero.In a pure inductive circuit the current lags the voltage by 90° because the inductive load always opposes the rate of change of current.

What is pure inductive circuit?

A Pure inductive circuit is one in which the only quantity in the circuit is inductance (L), with no other components such as resistance or capacitance. The current in this type of circuit lags behind the voltage by 90 degrees.

When pure inductor is connected across a supply?

Answer: In the purely inductive circuit above, the inductor is connected directly across the AC supply voltage. As the supply voltage increases and decreases with the frequency, the self-induced back emf also increases and decreases in the coil with respect to this change.

What is pure capacitive circuit?

A Pure Capacitor Circuit is a circuit that contains a pure capacitor with capacitance C farads. The capacitance of capacitors is the effect of storing electrical power in the electric field. It’s also known as the condenser. The current leads the voltage by 90 degrees in a pure AC capacitor circuit.
