When the number of turns in a coil is doubled without any change in the length of the coil, its self-inductance becomes
The total number of turns and cross-section area in a solenoid is fixed. However, its length L is varied by adjusting the separation between windings. The inductance of solenoid will be proportional to:
A long solenoid has a radius a and number of turns per unit length is n . If it carries a current i, then the magnetic field on its axis is directly proportional to
If the number of turns per units length of a coils of solenoid is doubled , the self- inductance of the soleniod will
Two solenoids of equal number of turns have their lengths and the radii in the same ratio 1:4. The ratio of their self inductances will be
Two solenoids of equal number of turns have their lengths and the radii in the same ratio 1:2. The ratio of their self inductances will be
If both the number of turns and core length of an inductor is doubled keeping other factorsconstant, then its self-inductance will be
