Q121 / 150 · MHT CET 2012 · Physics

A transformer is a device which converts

  • A
    low voltage at low current into high voltage at high current
  • Correct answer
    B
    high voltage at low current into low voltage at high current
  • C
    high voltage at high current into low voltage at low current
  • D
    electrical power into mechanical power

Solution

Transformer is a device used to convert high alternating voltage at low current into low alternating voltage at high current and vice-versa.

Hence, the correct answer is option: 'B'.
