Question

If the primary to secondary voltage ratio is 4:1 for a transformer, what is the secondary voltage if the primary voltage is 460 volts?

Answer 1

The secondary voltage is 115 V.

Step-by-step explanation:

The primary to secondary voltage ratio is given as 4:1 .

That is

`(V_p)/(V_s)=(4)/(1)=4`

We need to find what is the secondary voltage if the primary voltage is 460 volts.

That is

`V_p=460V`

Substituting in ratio equation

`(V_p)/(V_s)=4\\\\(460)/(V_s)=4\\\\V_s=(460)/(4)\\\\V_s=115V`

The secondary voltage is 115 V.
