New to electronics. Can't get my head around so many basic things but the application of KVL is bugging me the most.
I want to know what happens when Kirchoff's voltage law is broken. If for example, I have a 6V battery and a 4V load in a closed circuit. What happens here? The 4V load will consume or result in a 4V voltage drop. There will be a 2V "spare" unused voltage remaining before the current hits the negative terminal of the battery. In this instance, KVL's law is broken (well, I know it can't be).
I think the right way would be to put a resistor with a 2V voltage drop before the current hits the 4V load? That way KVL is not broken.
Which brings me to my next point: how do I know how much voltage drop a certain resistor will cause? If I used a 10 ohm resistor as a load on a 30V power supply, it will draw 3 amp current. Would this resistor cause a 30V voltage drop? If so, would that mean if I put two 10 ohm resistors on the same circuit (instead of one), each resistor will cause a 15V voltage drop?
