    Example answer:

    "A transformer works based on the principle of electromagnetic induction. It consists of two or more coils of wire, called the primary and secondary windings, wrapped around a common core. When an alternating current flows through the primary winding, it creates a changing magnetic field that induces a voltage in the secondary winding. The ratio of the number of turns in the primary and secondary windings determines the voltage transformation ratio. If the secondary winding has more turns than the primary winding, the transformer steps up the voltage, and vice versa."

  14. What is the importance of grounding in electrical systems?

    "In AC circuits, impedance is the total opposition to current flow, analogous to resistance in DC circuits. Impedance is a complex quantity that includes resistance (R), inductive reactance (XL), and capacitive reactance (XC). Inductive reactance is the opposition to current flow caused by inductors, while capacitive reactance is the opposition caused by capacitors. Impedance affects the phase relationship between voltage and current and is crucial for analyzing AC circuit behavior and designing AC systems."

  18. What is power factor and why is it important?
