Step Down Voltage Formula
The following formula is used to calculate the Step Down Voltage.
SDV = Ns/Np * Vp
- Where SDV is the Step Down Voltage (volts)
- Ns is the number of turns in secondary
- Np is the number of turns in primary
- Vp is the voltage in primary (volts)
How to Calculate Step Down Voltage?
The following example problems outline how to calculate Step Down Voltage.
Example Problem #1
- First, determine the number of turns in secondary. In this example, the number of turns in secondary is determined to be 34 .
- Next, determine the number of turns in primary. For this problem, the number of turns in primary is measured to be 14 .
- Next, determine the voltage in primary (volts). In this case, the voltage in primary (volts) is found to be 23.
- Finally, calculate the Step Down Voltage using the formula above:
SDV = Ns/Np * Vp
Inserting the values from above and solving the equation yields:
SDV = 34/14 * 23 = 55.85 (volts)
Example Problem #2
Using the same method as above, determine the variables required by the equation. For this example problem, these are:
number of turns in secondary = 3
number of turns in primary = 6
voltage in primary (volts) = 200
Enter these given values into the calculator or above yields:
SDV = 3/6 * 200= 100 (volts)
