These are the conceptual study questions to enrich your GK of 12th standard bifocal electronics subject. These questions will definitely compel you to think logically and to study the relevant chapter to understand the logic behind each of the question.
Conceptual study questions on Chapter 2, Power Supplies
- Why a rectifier circuit gives impure DC voltage rather than pure DC?
- What are the factors that affect the working of bridge rectifier circuit? Explain.
- Why capacitor filter circuit is suitable for low current applications? Explain.
- Why inductor filter circuit is suitable for high current applications? Explain.
- What will happen if we connect two diodes in anti-parallel combination in half wave rectifier circuit? Explain with reasons.
- If a diode in bridge rectifier circuit becomes faulty, then what will be the output condition of the circuit? Explain.
