Result in all units
Step-by-step solution
V₁/V₂ = N₁/N₂
What Is a Transformer?
A transformer is a device that steps alternating voltage up or down according to its turns ratio. The input and output voltages are proportional to the numbers of turns.
How is it calculated?
How Is It Calculated?
V_p ÷ V_s = N_p ÷ N_s
N: number of turns, p: primary, s: secondary.

Frequently Asked Questions
What happens to the current if the voltage increases?
In an ideal transformer power is conserved; if the voltage rises, the current falls by the same proportion.
