Alternating CurrentHard
Question
An inductor coil of inductance L is into two equal parts and both the parts are connected in parallel. The net inductance is :
Options
A.L
B.L/2
C.L/4
D.2L
Solution
The inductance is proportional to the length of the coil. So each part will have inductance 
In parallel their equivalent becomes

In parallel their equivalent becomes
