Also could some one go over this calc and why I got this answer wrong as well. 120 v ac primary and turns ration of 5:1 what is secondary voltage. my answer is 600 vac. I multiplied the primary voltage by the turns ratio

120*5 = 600 v ac

 

Vp : Vs :: Np : Ns

Because the primary has 5 turns for each turn of the secondary it is a step-down transformer.
120 : x :: 5 : 1
Read this as, 120 is to x as 5 is to 1

In the above ratio and proportion statement x must be 24.

 

Start at the beginning and state the relation between voltage and number of turns on the primary and secondary so I can see how you did your calculations.

 

Vp : Vs :: Np : Ns

Because the primary has 5 turns for each turn of the secondary it is a step-down transformer.
120 : x :: 5 : 1
Read this as, 120 is to x as 5 is to 1

In the above ratio and proportion statement x must be 24.

I forgot to divide both sides by 5 120/5=24 V AC

 

I forgot to divide both sides by 5 120/5=24 V AC

\(\frac{120}{x} = \frac{5}{1}\)

\(\Rightarrow x = \frac{120*1}{5} = 24\)
