Below is a picture of my very simple circuit.
There are three resistors 10 ohm, 100 ohm, and 10 kilohm. I connect them one at a time in serial fashion and measure voltage drop across them. When I measure battery voltage I get 6.5 Volt and this is what I expect as voltage drop on all of my measurements, but here is what I get:
- When I measure voltage drop across 10 ohm resistor I get 0.2 volt.
- When I measure voltage drop across 100 ohm resistor I get 1.0 volt.
- When I measure voltage drop across 10 kilohm resistor I get 5.8 volt.
Why do I get all these different readings and not something around 6.5 Volt?
P.S. On the image the circuit is not closed, but this is how I took picture, circuit is closed on all measurements.
