Question

The number of turns of a solenoid are doubled without changing its length and area of cross section .The self inductance of the solenoid will become ________ times​

Answer 1

Answer:

HOPE IT HELPS YOU :)

Explanation:

four

now, according to question, the number of turns in a coil is doubled without any change in inductance lending of the coil. so, inductance of coil becomes four times. hence, when the number of turns in a coil is doubled without any change in the length of the coil , its self inductance becomes four times

Answer 2

The number of turns of a solenoid are doubled without changing its length and area of cross section .The self inductance of the solenoid will become fourth times.
