Basic Electricity
Metric Number Prefixes

2. Dealing with Very Big and Very Small Numeric Values
In electronics we deal with incredibly large and incredibly small numbers
The international metric system allows for short hand dealing with the range of values
Give some examples of some of the very large and very small numbers we deal with. For instance voltage in household current and voltages received on an antenna. 2

3. Metric Units
Point out the most likely units the students will have to deal with on the exam like milli, micro, Kilo, Mega, etc. Using examples from test questions give the students some homework to convert between units. Remembering that Ohm’s Law, the basic units for voltage, current, and resistance are required. 3
