Question: In a transformer, if the primary coil has 200 turns and the secondary coil has 50 turns, what is the turns ratio?

Options:

Correct Answer: 1:4

Solution:

Turns ratio = Np/Ns = 200/50 = 4:1.

In a transformer, if the primary coil has 200 turns and the secondary coil has 50 turns, what is the turns ratio?

In a transformer, if the primary coil has 200 turns and the secondary coil has 50 turns, what is the turns ratio?

Step 1: Identify the number of turns in the primary coil. In this case, it is 200 turns.
Step 2: Identify the number of turns in the secondary coil. In this case, it is 50 turns.
Step 3: Write the formula for turns ratio, which is Turns Ratio = Np / Ns, where Np is the number of turns in the primary coil and Ns is the number of turns in the secondary coil.
Step 4: Substitute the values into the formula: Turns Ratio = 200 / 50.
Step 5: Perform the division: 200 divided by 50 equals 4.
Step 6: Write the turns ratio in the format of 'primary turns : secondary turns', which is 4:1.

Turns Ratio – The turns ratio in a transformer is the ratio of the number of turns in the primary coil (Np) to the number of turns in the secondary coil (Ns), which determines the voltage transformation.
