1SIR WHY R ,Lw ,1/Cw ARE TAKEN AS VACTORS EVEN THOUGH THE ARE NOT VECTORS AND HOW DOES IT HELP US TO SOLVE PROBLEMS
I`m having problems understanding LC oscillations........Can someone please explain????hcverma n resnick halliday is not helping me.....

62Just realize what is the phase lag...
and how it works.. it comes due to derivative..
if u take I = x sin kt
then V =I R in a pure circuit (without capacitor/ inductor ) will be in same phase as I
when the cirucit has impurities (i mean capacitor/ inductor) the purity will go adn there will be a difference in phase of V and I
The most basic is this much...
Now what you have to understand is that we can add phases just like vectors... (They are perpendicular)
A capacitor has Q which is integral of I
and an inductor uses dI/dt which is derivative of I
So the phases are perpendicular.. (with the resistance) and 180 degree with each other...
That is all...
After that phasor diagram or vector diagram which ever u want to call it and find the resultant

1yes sir i`ve undrstood this....but in hcverma there was something written,that in the case of a LC circuit the energy oscillates between the electric field in the capacitor and the magnetic field in the inductor....i am not quite making anything out of this.
