transformer voltage ratio calculator
Vs = Vp x (Ns/Np) is used to obtain the secondary voltage of a transformer. This is an association between primary input and secondary output by coil turns ratio.
Formula & Table Summary:
| Formula | Description |
|---|---|
| Vs = Vp × (Ns/Np) | Secondary voltage formula |
| Ns > Np | Step-up: Vs > Vp |
| Ns < Np | Step-down: Vs < Vp |

Frequently Asked Questions - Secondary Voltage Calculator:
Secondary voltage is the output voltage of a transformer obtained from the secondary coil.
Use Vs = Vp × (Ns/Np), where Vp is primary voltage and Ns/Np is turns ratio.
Secondary turns > primary turns, so secondary voltage > primary voltage.
Secondary turns < primary turns, so secondary voltage < primary voltage.
Yes, when Ns = Np, the transformer has 1:1 ratio and Vs = Vp.
Ideally no, but in practice voltage drops slightly under heavy load due to resistance.
It defines the relationship between primary and secondary voltages.
Yes, apply the same formula per phase for voltage ratio calculations.
Voltage is measured in volts (V), turns are unitless ratios.
No, this formula assumes an ideal transformer without losses.
