If the linear dimensions of the core of a cylindrical coil are doubled, the inductance of the coil will be (assuming complete winding over the core)
Text Solution
Verified by ExpertsThe correct answer is:
C
The inductance of a coil is given as 
where 
total number of turns of the coil; 
area of cross section of the coil 
radius of the core of the coil, 
length of the coil. If 
is doubled the total number of turns will be doubled
