A fully charged capacitor C with initial charge q 0 is connected to a coil of self inductance L at t = 0. The time at which the energy is stored equally between the electric and the magnetic fields is:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
In LC oscillation energy is transferred C to L
or L to C maximum energy in L is = 
LI 2 max
Maximum energy in C is = 
Equal energy will be when
LI 2 = 
LI 2 max
I = 
I max
I = I max sinωt = 
I max
ωt = 
or 
t = 
or t = 
t = 
=
