Basic Electronics » kirchhoff's voltage law...

I am pretty new to electronics and I am trying to self-teach myself... But I am reading up on Kirchhoff's voltage law and had a question. What is even the significance of this law? the total voltage drop across of all the loads are equal to the supply voltage.. when you measure all of the voltage drops with the multimeter's probes backwards, you get negative numbers; and when you add those numbers, you get 0. It seems common sense to me so I don't know why it is a law. Am I missing something about Kirchhoff's voltage law?

Hi jbolfiil,

I don't think you are missing anything, it is just a fundamental law of electronics that is absolutely true all the time. Once you start working out more electronics problems you will see that you end up using this law quite often.

alright hopefully once I start analyzing more circuits I will understand it more, thanks for the reply!
