Question
q:The electricity revised at an electric substation has a potential difference of 2.80 10^5V, if the required output is 440 V. what should be the ratio of the turns of the step-down transformer?
a: 28000/440= 636
a: 28000/440= 636

correct. Voltage is in direct proportion to the turns. Actually, it would be better written as 636/1 or 636:1, since it is a ratio
thanks!
thank you as well. I doubted myself on this problem and whether or not the rate was proportionate to the turns and voltage. Thank you for clarifying it.
