Question: In a transformer, if the primary coil has 100 turns and the secondary coil has 50 turns, what is the turns ratio? (2023)

Options:

Correct Answer: 2:1

Exam Year: 2023

Solution:

The turns ratio is 2:1, as the primary has twice the number of turns compared to the secondary.

In a transformer, if the primary coil has 100 turns and the secondary coil has 50 turns, what is the turns ratio? (2023)

In a transformer, if the primary coil has 100 turns and the secondary coil has 50 turns, what is the turns ratio? (2023)

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 50 turns.
Step 3: Write the turns ratio as the number of primary turns to the number of secondary turns. This is 100 turns (primary) to 50 turns (secondary).
Step 4: Simplify the ratio. Divide both numbers by 50. This gives you 2 (from 100) and 1 (from 50).
Step 5: Write the simplified ratio. The turns ratio is 2:1.

Turns Ratio – The ratio of the number of turns in the primary coil to the number of turns in the secondary coil in a transformer.
