And do you know that you can divide 1 by 0? Or any number by 0? The High school is just messing with people. Well, not mine. Then I found this beautiful thing. Haha. ----- For smartasses. 1/x where x->0, but ≠0 = ∞ Because x->0, but ≠0 is infinitely small number, dividing any random number by it = infinitely large number.
What I have written above is both correct and incorrect. Infinity is not a number. It is a concept and can't be measured. But in real life we work with approximations. Everything below the point of possible measurement suffices. While 1/0 is undefined it is a matter of perspective. In electronics, capacitor in DC circuit(0Hz) using the simple formula for Xc = 1/2pifC, where pi is 3.14.... and C is capacitance...f is frequency. You cant say I can't solve the problem. So, we assume using 1/x where x->0, but ≠0 = ∞. Thus, for us Capacitor becomes with infinite reactance. And for Inductors....They become just wires.... Who said that RMB can't be educational? Yes, even I can't remember everything, but have library and notes.... People assume that engineer = I know it all. Well, engineers just bring the perfect science into a imperfect world. And convert theories into working, real world solutions. Nobody knows it all or can remember everything. So, grasping the concepts is more important than being a parrot. Just create catalog.
