    H11P1 1.ω=2πf Capacitance C=1/((ω^2)L) 2.Bandwidth Δω = RL/L + 1/(Rc *C) 3.Capacitance C=1/((ω^2)L) 4.Bandwidth Δω = RL/L + 1/(R*C *C)

    with f= 860khz RL=4ohm Rc=490k L=0.65mHenry I can't get the bandwidth to check I get 44.1 with those values, still won't check, :c

    Δω = RL/L + 1/(Rc *C) #2.....4.0/0.65 + 1/(490k *44.1) .....=6.15384620012 is no good for me....help please
