Define self induction and self inductance. What is its unit? Write its dimensions.
Answers
Self-inductance of a coil is numerically equal to the amount of magnetic flux linked with the coil when unit current flows through the coil. The S.I. unit of self inductance is henry (H) or weber per ampere. 1 H = 1 Wb/A.
Answer:
In layman's words, we can also say that self-inductance is a phenomenon where a voltage is induced in a wire that carries current.
Explanation:
Step 1: The characteristic of a current-carrying coil that opposes or resists a shift in the current flowing through it is called self-inductance. This mostly happens because of the self-induced emf that the circuit produces.
Step 2: Self-inductance of a coil is numerically equal to the amount of magnetic flux linked with the coil when unit current flows through the coil.
The S.I. unit of self inductance is henry (H) or weber per ampere. 1 H = 1 Wb/A.
Step 3: Self inductance is defined as the induction of a voltage in a current-carrying wire when the current in the wire itself is changing. Self-inductance of a coil is numerically equal to the amount of magnetic flux linked with the coil when unit current flows through the coil.
So, Self-inductance of a coil is numerically equal to the amount of magnetic flux linked with the coil when unit current flows through the coil.
