Measure Current with Multimeters and DC Circuits

Materials:

2 x$5 Multimeter... 

Alligator Test leads for the current path

or Test Lead Kit(nice to have)

9v battery

9v battery connector

Resistor Assortment

Color LED of any type

Any breadboard

22guage solid stranded hookup(or jumper) wire

(solid wire is important for solderless breadboards, stranded wire works much better for soldering and mechanical flexibility)

Every single one of these things are useful and the basic starting point for hobby circuits.

(I'm listing local sources where you can walk into and purchase today. These things can be found cheaper and/or better quality online.)

DO NOT TRY TO MEASURE CURRENT UNTIL THE PROPER SECTION. Measuring current improperly will damage a multimeter.

1) First: see LED current example

We will be using a slightly used 9v DC battery for this example. (All batteries produce Direct Current (DC). All wall sockets produce Alternating Currents (AC).  

2) Measure the voltage at the 9v battery terminals with the Multimeter on the "DCV 20" setting. This setting measures DC voltages up to 20v. We expect ~9v from our 9v battery and chose a range setting greater than 9v. Try the other Voltage settings(DCV and ACV) BUT NOT The other settings and see what the resulting voltage reading produces. 

In progress!
