Section 2-1 Engineering Notation for Electronics

 Definition Engineering notation is a special form of power-of-10 notation where The coefficient must be between one and three  digits (not including zero) to the left of the decimal point. The exponent must be 0 or any multiple of 3 And since this is a power-of-10 system of notation, the base is always 10.

 Name Label Power-of-10 kilovolt kV x 103 volt V x 100 millivolt mV x 10-3 microvolt mV x 10-6

 Name Label Power-of-10 ampere (amp) A x 100 milliampere (milliamp) mA x 10-3 microampere (microamp) mA x 10-6

 Name Label Power-of-10 megohm MW x 106 kilohm kW x 103 Ohm W x 100

 Name Label Power-of-10 megawatts MW x 106 kilowatt kW x 103 Watt W x 100 milliwatt mW x 10-3 microwatt mW x 10-6

Procedure

 Important Terms being added or subtracted must have the same power of 10
2. Assign the common power of 10
3. Normalize the result, if necessary
