Can someone give some good website which explains abt damping in RLC series and parallel circuits?I am trying to understand the equations in RLC,how to get the A1 and A2 in the various damping conditions.
Looking forward to hearing from u guys.
With Thanx always for the help exended so far and all ur time
From my handbook, when 4*L/(R^2*C)=1, the circuit is critically damped (fastest response). When 4*L/(R^2*C)<1 the circuit is over damped (non-oscillating). When 4*L/(R^2*C)>1, the circuit is oscillating.
1. in order to find K,i' and i'' are found, put into the eqn 2(ur attachment) and equated to dV/dt.As its an ac supply we have an RHS but had it been DC it wud have been dV/dt=0
so Ld^2i/dt^2 +Rdi/dt+i/C=0
in which case we get k=0
does this mean there is no particular solution?
duh. :shock: ..i am sorry if i am asking really dum qs but i don get it
2. in case of a parallel circuit
the difference wud only be in the equation?
Icoswt=V/R+1/L integral V dt+C dV/dt
-wIsinwt=dV/R +V/L +v(0) +C d^2V/dt^2
the following procedures are the same as in series.
oh,oh but len i just came across some notes which say prticular solution is assumed
Acoswt+Bsinwt.....that is kcos(wt+phi)....sheesh...i am ?or it doesn matter?u can take both ways?kcos(wt+phi) and kcos(wt+phi+theta)?
