The ratio of voltage to current is called the resistance, and if the ratio is constant over a wide range of voltages, the material is said to be an "ohmic" material. If the material can be characterized by such a resistance, then the current can be predicted from the relationship:

    Ohm's Law - I=V/R or Electric Current = Voltage / Resistance

    The binomial theorem & Pascal's triangle. It's the only time I have ever used advanced math in my career (software engineering) back around 1996. Which is why I put it #1.

    I was an intern for a telecom company and the marketing department wanted to know how many of a certain type of circuit board to order. So someone gave the problem to the intern to play with for fun.

    I instantly recognized it was some sort of common statistical problem. But rather than waste time figuring out which one and taking a lot of time assuring it was correct, I wrote a quick software program to simulate the entire statistical problem. Then once I had the stats that I knew were right, I noticed they fit a certain pattern. And so then I reverse engineered and saw they fit the Pascal's Triangle\binomial theorem or something like that.

    So of course, I told my boss I solved it via the binomial theorem and Pascal's triangle and went through the formula showing it to him. And told him that I double-checked the work afterwards via a software simulation to prove it. That was a fun day for a 20 year old.
