FAQs on Parallel Resonance in RLC Circuit Video Lecture - Network Theory (Electric Circuits) - Electrical Engineering (EE)

1. What is parallel resonance in an RLC circuit?
Ans. Parallel resonance in an RLC circuit occurs when the impedance of the inductor and capacitor cancel each other out, resulting in a sharp decrease in overall impedance at a specific frequency.
2. How does parallel resonance affect the current in an RLC circuit?
Ans. At the resonant frequency in a parallel RLC circuit, the current is maximized due to the minimum impedance in the circuit, resulting in a higher flow of current.
3. What is the significance of parallel resonance in electrical engineering applications?
Ans. Parallel resonance is commonly used in electrical engineering applications to create filters, tuning circuits, and oscillators due to its ability to produce a sharp response at a specific frequency.
4. How does the quality factor (Q) relate to parallel resonance in an RLC circuit?
Ans. The quality factor (Q) of a parallel RLC circuit determines the sharpness of the resonance peak, with higher Q values indicating a narrower bandwidth and more selective frequency response.
5. How can parallel resonance be calculated in an RLC circuit?
Ans. Parallel resonance in an RLC circuit can be calculated using the formula f_resonant = 1 / (2π√(LC)), where f_resonant is the resonant frequency, L is the inductance, and C is the capacitance in the circuit.
