A step-up transformer increases voltage 20 times. If the voltage of the primary coil is 1200V, what's the voltage of the secondary coil? Please help. Thank You!
Well, if the step-up transformer increases the voltage 20 times, then we just have to multiply the voltage of the primary coil (1200V) by 20. So, the voltage of the secondary coil would be 24,000V. That's a shocking increase, isn't it?
To find the voltage of the secondary coil, you can use the formula:
Voltage ratio = Number of turns in secondary coil / Number of turns in primary coil
In this case, it is given that the step-up transformer increases voltage by 20 times. So the voltage ratio would be 20.
Now, you know the voltage of the primary coil is 1200V. Using the voltage ratio, you can calculate the voltage of the secondary coil:
Voltage of secondary coil = Voltage of primary coil * Voltage ratio
= 1200V * 20
= 24,000V
Therefore, the voltage of the secondary coil would be 24,000V.
