I am playing around with voltage drop resistor circuit, but the output voltage doesn't match the voltage I calculated.
This is the formula I am using
Vout = Vs*R2/(R1+R2)
The battery I am using is 9V, it measures about 9.4V using voltmeter.
I am expecting an output voltage around 8.6V-8.9V, but instead I get 6V.
Is there something that could also be affecting the output voltage or am I calculating the output voltage incorrectly? I am a beginner so there is a good chance of this.
I have measured the resisters individually and they both measure the correct resistance.
Here is an image of my breadboard, although I think I got everything wired correctly. (Yellow wire is output V+.)
My end goal is to drop about 0.5Voltage between the input and output.
