What is the primary:secondary turns ratio of this transformer ?
A step down transformer reduces a 130 V AC supply to 7 V AC in order to power a centrifuge motor with a power rating of 21 W.
What is the primary:secondary turns ratio of this transformer to the nearest whole number?

Explanation:
For a transfomer, the relationship between coil turns and voltage is:
#V_p,V_s# are the primary and secondary voltages
#N_p,N_s# are the primary and secondary number of coil turns
Here, we see that:
