I hope you have a better understanding now of powers of 10, and how they might be used in electronics.
Consider an electric charge of 1 Coulomb, which has a proton or electron count (depending on polarity) of roughly \(6.25 \times 10^\) would be 5.81 micro-units. Using this formula, we are able to express very large numbers and very small numbers much more efficiently than we would otherwise be able to. We will talk about how Engineering Notation differs from Scientific Notation in just a moment, but first, let's find out out exactly what \(4.32 \times 10^5\) means.įirst, we see that our base is 10 and our exponent is 5, so we know that we need to multiply the base (10) by itself equal to our exponent (5), so like mentioned before 10x10x10x10x10. In Scientific Notation the exponent can be any number, even negative numbers and zero. The exponent tells us how many times the base is to be multiplied by itself. The number 10 is called the base, the number 5 is called the exponent. In this case, it would be 4.32 times 10 to the power of 5. We have all probably seen something written in math class or in reading any kind of electronics text that looks like this: \(4.32 \times 10^5\) This is called scientific notation, or a power of 10. This entry is meant to help you understand powers of 10, scientific notation, engineering notation, and some metric prefixes.
