STANDARD Physics Self Inductance MCQ Question
Type: MCQ-conceptual-Medium-Class 12
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
A
1 : 2
B
2 : 1
C
1 : 1
D
1 : 4
Correct Answer
Option A
Detailed Explanation
Self inductance of a solenoid is proportional to the square of the radius and inversely proportional to the length. Given the ratio of radii and lengths, the ratio of self inductances is 1:2.
