I'm pretty much a beginner trying to wrap my head around the concept of voltage division within a circuit. To help myself out, I've come up with the following circuit.
[PLAIN]http://img401.imageshack.us/img401/801/voltagedivision.gif
I am having trouble determining the voltage between various points on the circuit.
Starting with Ohms law, I know that the current in the circuit is 15V/15 ohms (or, 1A).
Given the current, I can now determine the voltage between various points of the circuit.
Between points 1 and 2, the amount of voltage is:
V=1A x 5 ohms=5V
Between points 1 and 3, the amount of voltage is:
V=1A x (5 ohms + 5 ohms)
V=1A x 10 ohms=10V
Is this correct? Does the amount of voltage actually increase as your resistance increase? Sorry for sounding like a complete noob (which I am :) )
Additionally, say I need to supply 10V to a device that happens to be connected at point 6 on my drawing. Where is the voltage measured from? Assuming I'm correct, if you measure from point 1 to point 6, then there is 10V being supplied. However, if you measure from point 2 to point 6, there is only 5V being supplied. Which figure is accurate?
