11. Explain Ohm's Law and its applications.

    • Answer: Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them. Mathematically, it's represented as V = IR, where V is voltage, I is current, and R is resistance. It's fundamental to circuit analysis and is used to calculate voltage, current, or resistance in a circuit. Applications include designing circuits, troubleshooting electrical systems, and understanding power dissipation.

12. What are the different types of AC motors? Compare their characteristics.

    • Answer: Common AC motors include induction motors (single-phase and three-phase), synchronous motors, and universal motors. Induction motors are robust, simple, and widely used, but have slightly lower efficiency compared to synchronous motors. Synchronous motors offer high efficiency and precise speed control but require more complex starting mechanisms. Universal motors are used in applications requiring high starting torque but are less efficient and prone to wear.

13. Describe the function of a transformer and its principle of operation.

    • Answer: A transformer is a passive device that transfers electrical energy from one circuit to another through electromagnetic induction. It works based on Faraday's Law of induction. It consists of two coils (primary and secondary) wound around a common magnetic core. A varying current in the primary coil creates a changing magnetic field in the core, which induces a voltage in the secondary coil. Transformers are crucial for stepping up or stepping down voltage in power distribution systems.

14. Explain the concept of impedance in AC circuits.

    • Answer: Impedance is the total opposition to the flow of current in an AC circuit. Unlike resistance in DC circuits, impedance includes both resistance and reactance (due to inductors and capacitors). It's a complex quantity (represented as Z) with magnitude and phase angle. It's crucial for analyzing AC circuits and power calculations in AC systems.

15. What are some common troubleshooting techniques for electrical circuits?

    • Answer: Common troubleshooting techniques include visual inspection, using multimeters (to measure voltage, current, and resistance), using oscilloscopes (to analyze waveforms), checking circuit diagrams, using logic probes (for digital circuits), and systematic component testing. The approach often involves isolating sections of the circuit to identify the faulty component or connection.

16. Discuss the importance of grounding in electrical systems.

    • Answer: Grounding provides a safe path for fault currents to flow to the earth, preventing electric shock and protecting equipment from damage. It also helps to stabilize voltage levels and minimize electrical noise.

17. What are the differences between series and parallel circuits?

    • Answer: In a series circuit, components are connected end-to-end, so the current is the same through all components, and the total voltage is the sum of the individual voltages. In a parallel circuit, components are connected across each other, so the voltage is the same across all components, and the total current is the sum of the individual currents.

18. Explain the operation of a three-phase power system.

    • Answer: A three-phase system uses three AC voltage waveforms that are 120 degrees out of phase with each other. This provides higher power efficiency and smoother operation compared to single-phase systems. It's widely used in industrial and commercial applications.

19. What are some common types of semiconductor devices?

    • Answer: Common semiconductor devices include diodes, transistors (BJT, FET, MOSFET), integrated circuits (ICs), and thyristors. They are essential building blocks of modern electronic systems.
