question

(a) define the si unit of self-inductance.

(b) the self-inductance of a solenoid is l. if the number of turns per unit length in it is doubled and the area of cross-section is halved, find the new inductance of the solenoid.

 

 

 

 

 

 

a)the self-inductance of a coil is said to be one henry if the magnetic flux of one weber is produced when a current of one ampere flows through it.

b)
