In a step-up transformer the turn ratio is 1: 2 . A Leclanche cell (emf 1.5 V ) is connected across the primary. The voltage across the secondary is

Options

  1. A3.0 V
  2. B0.75 v
  3. Czero
  4. D1.5 V

Correct answer

C. zero

Step-by-step solution

Transformer works only in alternating current. Primary coil is connected to Lechlanche celli.e., connected by DC source, so voltage across secondary will be zero.
