Self-inductance:
- Self-inductance is the property of the current-carrying coil that resists or opposes the change of current flowing through it.
- This occurs mainly due to the self-induced emf produced in the coil itself.
- The self inductance, L = μr μ0 n2 A L
- The energy stored in the coil is given as, \(E=\frac{1}{2}LI^2\) where L = self-inductance, I = current flow in the circuit.
Explanation:
The energy stored in the coil is \(\frac{1}{2}LI^2\).
