Q1
In a step-up transformer, the number of turns in the primary winding is:
  1. Greater than the secondary winding
  2. Less than the secondary winding
  3. Equal to the secondary winding
  4. None of the above

Questions & Step-by-Step Solutions

In a step-up transformer, the number of turns in the primary winding is:
  • Step 1: Understand what a transformer is. A transformer is a device that changes the voltage of electricity.
  • Step 2: Know the two types of windings in a transformer: primary winding (input) and secondary winding (output).
  • Step 3: In a step-up transformer, the goal is to increase the voltage.
  • Step 4: To increase the voltage, the secondary winding must have more turns of wire than the primary winding.
  • Step 5: Therefore, in a step-up transformer, the primary winding has fewer turns than the secondary winding.
