I am just getting into electronics and been reading about voltage dividers, I wanted to build one myself. I have built the below schematics on a breadboard and I am not getting the voltages I want.
below are my calculations.
bleed = (20mA + 30mA) * .1 = 5mA R3 = 3.3/0.005 = 660Ω (really used a 680Ω)
R2 = (10 - 3.3) / 25mA = 268Ω (really used a 27Ω)
R1 = (12 - 10) / 55mA = 36Ω (really used a 33Ω)
After R1 I am getting a reading of 11.59V, and after R2 I am getting 8.26V.
I can't seem to figure out what I got wrong in my calculation.
