Transformer Turns Ratio

Voltage ratio equals turns ratio.

Formula

VpVs=NpNs\frac{V_p}{V_s} = \frac{N_p}{N_s}

Variables

V_p,V_sPrimary/secondary voltage
N_p,N_sTurns

Did You Know?

Transformers changed history by allowing electricity to travel vast distances at high voltage, then step safely back down.
