Let's take there is capacitor of capacitance c and inductor of inductance l.
00:08
So at this situation it's given that 80 % of the energy is stored in inductor's magnetic field.
00:20
That is at any moment equals to half l, i square.
00:29
I is the instantaneous current.
00:32
And energy stored in capacitor, ec, let's say, at any instant, is equal to half q square by c or q square by 2c.
00:51
So, at this instant, the energy stored 80 % of the energy, total energy, since total energy or maximum energy, maximum energy is equals to half l i0 square or q0 square by 2c.
01:27
Here i not is instantaneously maximum current that happens in the circuit and q0 is the maximum charge that is there on capacitor.
01:45
So, according to the question, according to the question, 80 % of half l i0 square is equals to half l.

I square...
