I recently made a voltage divider that uses a 10 ohm (top) and ~90 ohm (bottom) to divide a source voltage of 5v to 4.5v. The resistor values I used was somewhat arbitrary, in that I just picked a random top resistor value based on the resistors I had and calculated the bottom one.
My question: is there any advantage to use higher value resistor pairs over lower value resistors? Would a 100 top and 900 bottom have been better, for example? Or will the circuit work the same regardless of the resistance as long as the ratio remains constant?
