Hello. So I'm trying to create a small resistor network (voltage divider) that halves the voltage of a measuring device. I have a measuring device that can only go up to 20 Volts, and the battery I need to measure can go up to 21 volts. So essentially I want to create a voltage divider to halve the voltage, and then just multiply by two when I analyze the data.
The measuring device has an input impedance of 122k. If I want to halve the 20 volts to 10 volts, wouldn't I just need another resistor of 122k in series?
If not, how would I go about compensating for internal resistance?
Also, how would I create the actual circuit? I don't have much experience with soldering or building physical circuits.
I know this is a lot, and I thank you for any time you have given me today.
