The self-inductance of a coil is L. Keeping the length and area same, the number of turns in the coil is increased to four times. The self-inductance of the coil will be
Self-Induction Self-induction is the property of a coil by virtue of which the coil opposes any change in the strength of current flowing through it by inducing an emf in itself. This induced emf is also called back emf. When the current in a coil is switched ON, then the self induction opposes the growth of the current and when it is switch OFF, then the self-induction opposes the decay of the current.Calculate the inductance of an air core solenoid containing 300 turns, if length of solenoid is `12pi cm` and its cross-sectional area is `4
There are two long co-axial solenoids of same length `l`. The inner & outer coils have radii `r_1 & r_2` and number of turns per unit length `n_1 & n_2`, respectively. The ratio of mutual inductance to the self-inductance of the inner coil
A long solenoid has 1000 turns. When a current of `4 A` flows through it, the magnetic flux linked with each turn of the solenoid is `4 xx 10^(-3)Wb`. The self-inductance of the solenoid
