Which condition is known as resonance in an RLC circuit?

Which type of power factor is produced by a practical inductor in an AC circuit?

Which statement is correct for a balanced 3-phase system connected to a load?

Which condition represents resonance in a series RLC circuit?

Which of the following statements related to a delta-connected 3-phase system is INCORRECT?

For an R-L-C series circuit connected to an input signal of 4 Vp-p, 1 kHz periodic sinusoidal AC signal, the voltage drop across the resistor R measured with CRO displays a sine wave occupying 2 units total height with the volts/div knob at 1 V. What is the approximate RMS current for the circuit if R = 10 Ω?

The Q-Factor (Quality Factor) of a coil is a critical parameter in resonant circuits. How is it mathematically defined in terms of the coil's inductive reactance (XL) and its internal DC resistance (R)?

In a single phase AC circuit supplied with a voltage V and drawing a current I, if φ is the phase angle between V and I, what is the expression for real power P consumed by the circuit?
