  1. Question 1

    Q1. A transformer is used to step-down the voltage in a household appliance. What is the effect on power consumption?

    • A) Increased
    • B) Decreased
    • C) No change
    • D) Depends on resistance

    Answer: No change

    Explanation: The power consumption of a household appliance is determined by its resistance, not by the voltage. Stepping down the voltage using a transformer does not affect power consumption. The other options do not describe the effect correctly.
