Hi I'm new here (found the site after searching for an age for help)
I'm having some issues with the above rule that I think someone might be able to help with.
I'm working on a question similar to the one attached. I understand the basic "equation" for Voltage Divider (my version is in the picture) but I can't figure out how to find the voltage at point a. Can't remember any rule I learnt for it and I've a test tomorrow. Any help at all would be appreciated (and duly awarded with +rep or something).
BTW As for attempts, I have spent an hour or two searching lecture notes to no avail. I can do similar questions that don't involve 2 resistors on one "branch" easily enough.
