Question

Explain the phenomenon of self induction and mutual induction. Define coefficient of self induction and mutual induction. Write the SI unit and dimensions of coefficient of self induction. A potentiometer wire has a length of 4 m and a resistance of 5 Ω. What resistance should be connected in series with a potentiometer wire and a cell of e.m.f. 2 V having internal resistance 1 Ω to get a potential gradient of 10–3 V/cm

Answer 1

Answer:

Self Induction / Self inductance

=> The process in which when we change the current in a coil/circuit an induced EMF is induced in that coil or circuit and this process is called self inductance.

Coefficient of self inductance:- It’S unit is Weber/Amperes ( Wb/A )
