Experiment 7 - LEDs in a Series and Parallel Circuit

For a circuit with a large number of LEDs you use a combination of series and parallel circuits.

When you want to use six or more LEDs in your circuit, you can increase the voltage or adapt the circuit... Series and parallel circuit of six LEDs. (Enlarge) All six LEDs light up at normal brightness.

Circuit diagram of six LEDs in series and parallel.

Until now you have only worked with red LEDs. In the next experiment you examine what changes with different colored LEDs.
