I have what may be a simple question for some, but for me... I just can't figure it out. I have a AA battery which my multimeter is reading to have 1.0V. When I use the battery as shown in the image below (in parallel with a 10Ω resistor) my voltage through the resistor (measured at points A and B) shows to be 0V. However, when I connect a bigger resistor (10kΩ), the voltage across the resistor shows 0.68V. The voltage keeps increasing if I keep increasing the resistor value. Why is my voltage being reduced to 0 when the resistor in parallel is of low value, but increases when the resistor has a bigger value? The circuit: Edit: I fixed a typo there.
