So I am totally new to learning/using electronics & I have a question regarding resistors. I’m working on a project in which i am trying to take in 0-30v and scale it down to 0-5v so the Arduino can read it. I attached a diagram/picture of my work. I choose my resistors based upon the diagram/formula i calculated. I also double checked my work using: http://www.raltron.com/cust/tools/voltage_divider.asp
My question is about the specific selection of resistors. I have arbitrarily selected R1 = 5000 & R2 = 1000 based off the resistors i have in my kit. But I could also potentially go with R1 = 1000 & R2 = 200 or many other different combinations. What is the potential benefits or using higher or lower scaled pair of resistors if any?
