Question

In an AC. circuit containing inductance only, the current.

Answer 1

Alternating current

1. Alternating current is a type of electricity that has its magnitude and polarity vary at regular intervals.
2. In contrast to Direct Current (DC), which only flows in one direction, it can also be described as an electrical current that alternates or reverses its direction on a regular basis.

Inductance

1. In electromagnetism and electronics, inductance is the tendency of an electrical conductor to resist a change in the electric current passing through it.
2. The flow of electric current creates a magnetic field around a conductor.

Formula for inductance

$L=\frac{\varphi \left(i\right)}{i}[whereL=induc\tan ce,\varphi =magneticfluxofcurrent(i),(i)=current]$

Pure Inductive circuit

1. A circuit with only inductance (L) and no other values such as resistance or capacitance is referred to as a "pure inductive circuit."
2. The current in this circuit is 90 degrees behind the voltage. In circuits with predominantly inductive loads, the current lags the voltage.
3. Because of the generated electromotive force, current flows via an inductive load. The voltage in the previous description provides the current.

In an a.c. circuit with just inductance, the current is 90 degrees behind the voltage.
