Metric Notation, Electrical Prefixes, and Powers of 10


Overview

Overview

  • Powers of 10

  • Metric Notation & Electrical Prefixes

  • Math Operations


Overview1

Overview

  • You will studynumerous electrical measurements in electronics. These measurements often involve very large and very small numbers. You will often have to add, subtract , multiply and divide these numbers. It takes quite a bit of time to perform these calculations. For this reason, powers of ten and metric notation are used to simplify calculations.


Powers of ten

Powers of Ten

Exponent

Number that shows how many times the base number is used as a multiplier

3

4 X 10

Base Number

Coefficient

Always 10 in the decimal number system

  • A number multiplied by the power of ten


Powers of ten1

Powers of Ten

  • Moving the decimal affects the value of the exponent.

    • Decimal moves right—exponent increases

    • Decimal moves left—exponent decreases

3

4 X 10 = 4000.

Powers of Ten

  • Moving the decimal affects the value of the exponent.

    • Decimal moves right—exponent increases

    • Decimal moves left—exponent decreases

Metric notation electrical prefixes

Metric Notation / Electrical Prefixes

  • A metric prefix is a group of letters with a specific meaning attached to the beginning of units of measure such as mile, foot, meter, or liter.

    • The table below lists powers of ten, metric prefixes and symbols commonly used in electronics.


Math operations

Math Operations

  • Addition

  • Subtraction

  • Multiplication

  • Division


Addition and subtraction

Addition and Subtraction

  • Rule-The exponent values must be the same before adding or subtracting.

    Example

4 X 106

+ 4 X 106

  • 4 X 106

  • - 2 X 106


Addition and subtraction1

Addition and Subtraction

  • Rule-The exponent values must be the same before adding or subtracting.

    Example

4 X 106

+ 4 X 106

8 X 106

  • 4 X 106

  • 2 X 106

  • 2 X 106


Multiplication

Multiplication

  • Rule- Add the exponent values;then multiply the numeric coefficients.

    Example

4 X 103

X 4 X 106

16 X 109


Division

Division

  • Rule- Subtract the exponent values and divide the numeric coefficients.

    Example

4 X 106

÷ 2 X 103


Division1

Division

  • Rule- Subtract the exponent values and divide the numeric coefficients.

    Example

4 X 106

÷ 2 X 103

2 X 103


Summary

Summary

  • Solving math problems in electronics using very large and small numbers can be difficult and time consuming. Very large and small numbers consist of many digits, often zeros. Anyone who has worked with a lot of zeros knows that mistakes in math are easy to make. Powers of 10 and metric prefixes are shorthand methods for expressing very large and very small numbers. Using this shorthand will allow you to perform calculations with greater accuracy.
