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