+//Problem 28.10: A coil of inductance 351.8 mH and resistance 8.84 ohm is connected in series with a 20 μF capacitor. Determine (a) the resonant frequency, (b) the Q-factor at resonance, (c) the bandwidth, and (d) the lower and upper -3dB frequencies.
+
+//initializing the variables:
+R = 8.84; // in ohms
+L = 0.3518; // IN Henry
+C = 20e-6; // IN fARADS
+
+//calculation:
+//Resonant frequency,
+fr = 1/(2*%pi*((L*C)^0.5))
+wr = 2*%pi*fr
+//Q-factor at resonance, Q = wr*L/R
+Qr = wr*L/R
+//bandwidth,.(f2 − f1)
+bw = fr/Qr
+//the lower −3 dB frequency
+f1 = fr - bw/2
+//the upper −3 dB frequency
+f2 = fr + bw/2
