So I understand the practicle application of measuring voltage drops accross a resistor.
But why does it work that way? If I measure from a point before a resistor, and then a point after the resistor, how is my multimeter measuring that voltage?
You're essentially creating an alternate path for the voltage to travel... wouldn't that alter the current accross the circuit and therefor change the voltage drop of the resistor?
If I tried to measure two points on a circuit without going through a component, shouldn't that still give me a voltage value?
I've learned a lot of this a long time ago, but haven't utilized the knowledge and much of it's lost. Google hasn't helped me much, so I wondered if I could get help here.
