Q1.	A 200 turn coil has an inductance of 12 mH. If the number of turns is increased to 400 turns, all other quantities (area, length etc.) remaining the same, the inductance will be
A.	6 mH [Wrong Answer]
B.	14 mH [Wrong Answer]
C.	24 mH [Wrong Answer]
D.	48 mH [Correct Answer]
View Answer 21 -21 Explanation:- Answer : D Discuss it below : Prakash Majumder Said on 2018-09-19 09:27:42 L is proportional to N^2 Hence, L1/(N1)^2=L2/(N2)^2 therefore, 16(400)^2/(200)^2=L2 =>L2=48mH !!
