Inductive Circuit and Inductive Reactance
An inductive circuit consists of an inductor (L) which provides opposition to the flow of alternating current. This opposition is known as inductive reactance (XL) and is directly proportional to the frequency of the AC signal and the inductance of the coil.

Effect of Inductance or Inductive Reactance on Circuit Current
When the inductance (L) or inductive reactance (XL) in an inductive circuit increases, the circuit current decreases. This is because as the inductance or inductive reactance increases, it offers more opposition to the flow of current. The increased opposition results in reduced current flow through the circuit.

Explanation
1. **Inductive Reactance (XL) and Current Relationship**:
- In an inductive circuit, the current lags behind the voltage due to the presence of inductive reactance.
- The higher the inductive reactance, the greater the phase shift between voltage and current, resulting in a decrease in current flow.
2. **Opposition to Current Flow**:
- Inductors store energy in the form of a magnetic field, which resists changes in current flow.
- As inductance or inductive reactance increases, the inductor offers more opposition to the changing current, reducing the overall current in the circuit.
3. **Mathematical Relationship**:
- The relationship between inductive reactance, inductance, and current flow is given by Ohm's Law for AC circuits, where XL = 2πfL.
- As XL increases with higher inductance or frequency, the current decreases inversely proportionally.
Therefore, in an inductive circuit, when inductance or inductive reactance increases, the circuit current decreases due to the increased opposition offered by the inductor to the flow of alternating current.
