Question
Since the normal voltage in a home is 120 V, what is used to bring the voltage to that level?
a direct transformer
a step-down transformer
a step-up transformer
an alternating transformer
a direct transformer
a step-down transformer
a step-up transformer
an alternating transformer
Answers
A step-down transformer is used to bring the voltage from higher levels (such as the ones used for power transmission) to the standard 120V voltage required for household appliances. Therefore, the correct answer is a step-down transformer.
