Hello everyone, I am really new to electronics and have been reading Electronics for dummies, and am readying myself to move on to something a bit more sophisticated. Something that has been hard for me understanding is circuits that don't seem to have a start or an end. I do quickly understand the flow of a circuit if the battery is shown in the circuit and connected. For example, I cannot understand where this starts an ends, and why is configured the way it is. I plan to major in electronics, but I want to make sure I get the raw fundamentals of it, before I even attempt to make a simple sound amplifier. I would also like to ask. Where I could learn about multi meters and where I need to place probes, in order to find proper current, resistance through out a circuit, and voltage drops and what not?
