Please help me!!!

A transformer is used to convert 120 V to 8.6 V in order to power a toy electric train. If there are 260 turns in the primary, how many turns should there be in the secondary?

**Best answer:**

*Answer by jrrymiller*

The voltage ratio is the same as the turns ratio. So the easiest solution is:

120/8.6 = 260/X whoops I got the X on the bottom, no problem

8.6/120 = X/260 and X = 8.6*260/120

= 18.63 turns

actually you would probably put 19 turns as a practical matter.
