And it can be cumbersome to write out those numbers. All of those zeros take up a lot of space and it's easy to miscount them at a glance. So, to make large and small numbers easier to work with, we use a common set of prefixes to describe quantities based on powers of 10. These metric prefixes are attached to the front of a base unit like volts, amps, or ohms to indicate a multiple or fraction of that unit. This table contains the most common prefixes you'll encounter when working with electronics and have included a copy of it in the exercise files for this video that you can use as reference. The prefixes on the top half of the chart, kilo, mega and giga represent multiples of a base unit that are greater than one. And the prefixes on the bottom half of the chart,…
