RLC Circuits and Resonance - General Questions (6)

What is the range between f₁ and f₂ of an RLC circuit that resonates at 150 kHz and has a Q of 30?

What is the Q (Quality factor) of a series circuit that resonates at 6 kHz, has equal reactance of 4 kilo-ohms each, and a resistor value of 50 ohms?

How much current will flow in a 100 Hz series RLC circuit if V_S = 20 V, R_T = 66 ohms, and X_T = 47 ohms?

In a parallel RLC circuit, which value may always be used as a vector reference?

What is the applied voltage for a series RLC circuit when I_T = 3 mA, V_L = 30 V, V_C = 18 V, and R = 1000 ohms?
