Lab 3 - Using a Multimeter

Description:

The multimeter is a very important tool to verify if our components are working on the breadboard.  One of the things we can verify is continuity.  In other words to see if a the component or wire conducts electricity, so if it does our multimeter will make a beep sound.  The continuity setting can also tell us if there is an open on the circuit board.  Another setting we can use to verify out parts is measure voltage.  We can measure our power source or the individual components on a circuit board.  Using Kirchhoff's Law we can make sure the voltage drops across the components of a circuit board equal the power source.  There are two settings for measuring voltage, which are AC and DC.  The multimeter can also measure resistance.  Components like resistors will have different amounts of resistance, which can be determined by using the 4 Band Code.  The first two stripes of colors represent the first two digits in the number.  The third color tells you haw many zeros to add after the first two digits.  The fifth band tells you the percent tolerance.
