Hi. I have been wondering whether it is possible to use KVL in this way:
If I have a series circuit where there are a number of components in series, but the voltage drops are difficult to calculate, or variable, and I want to ensure what the voltage is at a certain node (perhaps to make sure that there is a certain voltage available at a part of a circuit), I could place at least two resistors parallel to this circuit as a voltage divider.
I've drawn what I mean. Select A and B to ensure an adequate supply to the bottom two components.
