What happens to the inductance when the current in the coil becomes do...
Effect of Current on Inductance:
Inductance is a property of an electrical circuit that opposes changes in current. When the current in a coil becomes double its original value, the inductance of the coil also changes.
Explanation:
Direct Proportionality:
- In an ideal coil, the inductance is directly proportional to the current flowing through it. This means that when the current doubles, the inductance also doubles.
Mathematical Relationship:
- The inductance (L) of a coil is given by the formula L = (μ*N²*A)/l, where μ is the permeability of the core material, N is the number of turns, A is the cross-sectional area, and l is the length of the coil.
- When the current increases, the magnetic field produced by the coil also increases, leading to a higher inductance.
Practical Implications:
- When the current in a coil becomes double its original value, the inductance of the coil will also double. This has implications for various applications in electrical engineering, such as inductors used in power supplies, transformers, and electric motors.
Therefore, when the current in the coil becomes double its original value, the inductance of the coil will also double.
