Oh dear, oh dear, oh dear  :palm: The sum of all the voltages around a loop is equal to zero.
IonizedGears:
No, the sum of all the voltage drops in a loop minus the applied or source voltage =0.

No need to count the source twice. Sources aren't special objects, they're all voltage drops.

If you subtract the "source voltage", that method cannot cope with multiple sources, especially ones external to the loop, which does not have to exist in isolation for KVL to work.

Example where that method fails (your money refunded 100% if my math is wrong ;)):
IonizedGears:
:/ that isn't what they taught me in school

Seriously, don't they even teach Kirchhoffs laws properly these days? Because what you wrote - twice - is utter bullshit. Twice.
