This is my question 1. and this is my question 2. in a RLC series circuit show above are replaced following : R=500Ω L=0.4mH and C=100pF the circuit is connected to the terminals of an ac source with an rms voltage of 1V, and a variable frequency calculate the following A) resonant frequency ans: f = 1/2*pi*sqrt(LC) = 1/(2*pi*sqrt(0.0004 * 100 * 10^-12) = 795.77 Khz b) the inductive and capacitive reactance at resonance ans: XL = 2*pi*f*L = 2*pi* 795.775*10^3*0.0004 = 2000 ohm Xc = 1/(2*pi*f*C) = 1/(2*pi* 795.775*10^3 * 100 * 10^-12) = 1999.9998 ohm C) the impedance at resonance ans : impedence of resonance is resistance of circuit : z = R = 500 ohm D) the rms current at resonance ans: I = V/R = 1/500 = 0.002A E) the rms voltage across each element at resonance Ans: Vr = IR = 0.002 * 500 = 1V VL = IXL = 0.002 * 2000 = 4V Vc = IXc = 0.002 * 1999.99 = 3.99998 V So am i doing it right?? because i got another reply that says this :
If you want to go back and track your units, I will look through this. Otherwise it's not worth my time.
