I've been trying to understand this section, but I am thoroughly stuck.
How does Null Detection work? Here's what I've gathered:
- The Voltage entering R2 is 24V; exiting is 12V, equalling a 12V drop.
- What should the Adjustable Voltage Source be set to?
- If its at 24, theres no difference in Voltage along the bottom path, but wouldn't 24V be dropped across the Voltmeter, allowing for 0V to enter point labeled 2 and 12V to be entereing point labeled 1?
- On the other hand, how is the Voltmeter not forming a parallel resitance with R2? Is it because the A.V.S. is indeed set to 24V, effectively stopping any current flow from heading from the A.V.S to R2? If this is the case, it just goes back to the previous point's question.
Ugh. I hate being stuck; I just can't move on if I am. I'll go learn some Ruby Programming while someone (hopefully) clears this up.
Thanks everyone for your help in advance, and sorry to post such a n00b question.
