| Voltage | |
|---|---|
| In SI base units | kg⋅m2⋅s−3⋅A−1 |

What is dimensional formula of L?
Let us now calculate the dimensional formula of inductance L. For this we will use Faraday’s law, which use that the emf induced in a coil is equal to E=Ldidt ….. (iii), where l is the inductance of the coil and i is the current in the coil. This implies that the dimensional formula of L is [L]=[E][didt].
Where is self inductance used?
The self-inductance of a circuit is used to describe the reaction of the circuit to a changing current in the circuit, while the mutual inductance with respect to a second circuit describes the reaction to a changing current in the second…
What is self inductance and its unit?
S.I., the unit of self-inductance is Henry. i.e., 1 Henry = 1 Weber turns / Ampere. or 1 Henry = 1 Volt / ampere/second. Self-inductance of a coil is 1 Henry when a current change at the rate of 1 amp/sec through the coil induces EMF of 1 volt in the coil.
How does self inductance occur?
Self inductance is defined as the induction of a voltage in a current-carrying wire when the current in the wire itself is changing. In the case of self-inductance, the magnetic field created by a changing current in the circuit itself induces a voltage in the same circuit.
What is the importance of self inductance?
Self-inductance in electrical circuit is equivalent to mass or inertia in mechanical system. As inertia opposes any change of mechanical motion, similarly the presence of self- inductance offers resistance to any change of current or voltage.
What is the self inductance of a coil?
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.
