Questions & Step-by-Step Solutions

In a transformer, if the primary coil has 100 turns and the secondary coil has 200 turns, what is the turns ratio? (2021)
  • Step 1: Identify the number of turns in the primary coil. In this case, it is 100 turns.
  • Step 2: Identify the number of turns in the secondary coil. In this case, it is 200 turns.
  • Step 3: Write the turns ratio as the number of turns in the primary coil to the number of turns in the secondary coil. This gives us 100:200.
  • Step 4: Simplify the ratio. To simplify 100:200, divide both numbers by 100. This results in 1:2.
  • Step 5: State the final simplified turns ratio, which is 1:2.
