In a transformer, what does the term 'turns ratio' refer to?
  1. The ratio of primary to secondary voltage
  2. The ratio of primary to secondary current
  3. The ratio of primary to secondary turns
  4. The ratio of power input to output

Questions & Step-by-Step Solutions

In a transformer, what does the term 'turns ratio' refer to?
  • Step 1: Understand that a transformer has two main parts: the primary winding and the secondary winding.
  • Step 2: The primary winding is where the input voltage is applied.
  • Step 3: The secondary winding is where the output voltage is taken.
  • Step 4: Count the number of turns (loops of wire) in the primary winding.
  • Step 5: Count the number of turns in the secondary winding.
  • Step 6: The turns ratio is found by dividing the number of turns in the primary winding by the number of turns in the secondary winding.
  • Step 7: This ratio helps determine how the voltage changes from the primary to the secondary side.
