Questions & Step-by-Step Solutions
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.
