1.	State and define the SI unit of self inductance. Give its dimensions. OR Write the SI unit and dimensions of the coefficient of self induction.
Answer» The SI unit of self inductance or coefficient of self induction or inductance as it is commonly called is called the henry (H). The self-inductance of a coil is 1 henry, if an emf of 1 volt is induced in the coil when the current through the same coil changes at the rate of 1 ampere per second. The dimensions of self inductance or coefficient of self induction are [ML²T^-2 I^-2 ]. 1 henry = 1 H = 1 V/A.s = 1 T.m² /A [ Note : The unit henry is named in honour of Joseph Henry (1797-1878) US physicist.]

Answer»

The SI unit of self inductance or coefficient of self induction or inductance as it is commonly called is called the henry (H).

The self-inductance of a coil is 1 henry, if an emf of 1 volt is induced in the coil when the current through the same coil changes at the rate of 1 ampere per second.

The dimensions of self inductance or coefficient of self induction are [ML²T^-2 I^-2 ].

1 henry = 1 H = 1 V/A.s = 1 T.m² /A

[ Note : The unit henry is named in honour of Joseph Henry (1797-1878) US physicist.]
