Guest,

If you haven't been to college yet, don't worry, they'll teach you these things.

If you're already in college, dont' worry, they'll teach you these things eventually.

If you've finished college, don't worry, just re-enrol.

And if you are a fully trained up sparky, visit the doctor because obviously something has gone adrift upstairs! lol

And if you're trying to design circuits without knowing these formulae, don't worry too much about them. You probably won't be around for anyone to blame for anything that goes wrong with your design for much longer.

"On another occasion it happened that a certain heathen came before Shammai and said to him, "Make me a proselyte, on the condition that you teach me the whole Torah while I stand on one foot." Thereupon he chased him away with the builder's cubit that was in his hand. When he came before Hillel, (he also asked Hillel to teach him the entire Torah while standing on one foot) Hillel replied, "What is hateful to you, do not do to your neighbor: that is the whole Torah while the rest is commentary; go and learn it."
