Sinopsis
The electrical quantities you will encounter while working in the fi eld of electronics are often extremely small or extremely large. For example, it is not at all uncommon to work with extremely small decimal numbers such as 0.000000000056 or extremely large numbers such as 1,296,000,000. To enable us to work conveniently with both very small and very large numbers, powers of 10 notation is used. With powers of 10 notation, any number, no matter how small or large, can be expressed as a decimal number multiplied by a power of 10. A power of 10 is an exponent written above and to the right of 10, which is called the base. The power of 10 indicates how many times the base is to be multiplied by itself. For example, 10 3 means 10 x 10 x 10 and 10 6 means 10 x 10 x 10 x 10 x 10 x 10. In electronics, the base 10 is common because multiples of 10 are used in the metric system of units.
Scientifi c and engineering notation are two common forms of powers of 10 notation. In electronics, engineering notation is generally more common than scientifi c notation because it ties in directly with the metric prefi xes so often used. When a number is written in standard form without using any form of powers of 10 notation, it is said to be written in decimal notation (sometimes referred to as fl oating decimal notation). When selecting a calculator for solving problems in electronics, be sure to choose one that can display the answers in decimal, scientifi c, and engineering notation.
