Self-inductance of a coil is defined as the ratio of self-induced emf to the rate of change of current in the coil.
Higher the self-inductance of a coil, longer the delay in establishing a steady current through it.

Effects of Self-Inductance on a Coil:
Inductance is the property of a coil that resists changes in current flowing through it. Self-inductance is a measure of this property in an isolated coil.
Delay in Establishing Steady Current:
When the self-inductance of a coil is higher, it leads to a longer delay in establishing a steady current through it. This is because the coil resists changes in current, causing a lag in reaching a stable flow of electricity.
Explanation:
- When a coil has high self-inductance, it generates a back EMF (electromotive force) that opposes the changing current. This back EMF hinders the flow of current, resulting in a delay in reaching a steady state.
- The back EMF induced in the coil due to self-inductance counteracts the applied voltage, thereby slowing down the rate at which current builds up.
- As a result, it takes more time for the current to reach its maximum value in a coil with higher self-inductance, leading to a longer delay in establishing a stable current flow.
In conclusion, the self-inductance of a coil directly affects the delay in establishing a steady current through it. Higher self-inductance results in a longer delay due to the opposition offered by the back EMF induced in the coil.
