This is your last lab on parallel circuits. Use what you have learned thus far.
Watch the example video, and then perform the lab.
Note | ||
You can add a jumper wire in front or back of the LED to measure the current as shown in the example below. Clamp the meter around the jumper wire and zero it. Then press the button to turn on the LEDs and measure the current. This will give the best results. |
Note | ||
To measure the current into the push button, clamp the Extech around the wire coming into the push button. Clamp the meter around the wire and zero it. Then press the button to turn on the LEDs, and measure the current. This will give the best results. |
Think About it! | ||
In a parallel circuit what stays the same, the voltage or the current? How much current does a single LED use? How much current can the power supply provide? |
