As you can see from the picture, shouldn't the 100 Ohms be the only current influencing factor at whatever the voltage it is supplying? How does Potentiometer on the right side cause decrease in current when I am measuring the current even before current crosses potentiometer?
For example, at 4 V, 100 Ohm(fixed) on the left / 1000 Ohm(potentiometer) on the right I measured 3.59mA
Then at 4 V, 100 Ohm(fixed) on the left / 2000 Ohm(potentiometer) on the right I measured 1.88mA
Am I wrong? Clearly experiment say so...
