  1. Question 1

    Q1. A transformer that increases the output voltage above the input voltage is called a:

    • A) Step-down transformer
    • B) Isolation transformer
    • C) Current transformer
    • D) Step-up transformer

    Answer: Step-up transformer

    Explanation: A step-up transformer has more turns in the secondary coil than the primary, so the output (secondary) voltage is higher than the input (primary) voltage. Step-down transformers do the reverse, reducing voltage, and both types rely on electromagnetic induction.
