Explanation:
The primary to secondary voltage ratio is given as 4:1 .
That is
[tex]\frac{V_p}{V_s}=\frac{4}{1}=4[/tex]
We need to find what is the secondary voltage if the primary voltage is 460 volts.
That is
[tex]V_p=460V[/tex]
Substituting in ratio equation
[tex]\frac{V_p}{V_s}=4\\\\\frac{460}{V_s}=4\\\\V_s=\frac{460}{4}\\\\V_s=115V[/tex]
The secondary voltage is 115 V.
