Effec of ac on pure inductance in tamil

EFFECT OF A.C ON PURE
INDUCTANCE (L)
When an alternating voltage is applied to an inductive coil, the back emf produced due to self-inductance opposes the rise or fall of current through it. Since there is no ohmic drop, the applied voltage has to overcome this induced e.m.f only.
Power (P):
Power is generally defined as the rate at which the work is done
Real power (P):
It is a resistive power that is dissipated as heat. Its unit is Watts.
It is always positive. P=VI cosθ
Reactive Power (Q):
It is the product of the power developed in reactance of the circuit. Its unit is Volt-Ampere Reactive (VAR). Q=VI sin θ
Apparent Power (S):
It is defined as the product of magnitude of voltage and magnitude of current. It is measured in Volt-Ampere (VA). S=VI
Power Factor (cos ):
Power actor is defined as the cosine value of phase angle between the voltage and current. Or Power factor is defined as the ratio of real power to apparent power. It has no unit. It is always less than unity.

Inductor block ac but how it's possible

[@NithyaSri34653]

Sir.....diploma ccircuit theory exam eppo sir...???
