Below are 3 circuit diagrams illustrating the usage of capacitors and the effects of capacitors in series and parallel.
After you've built these circuits on a breadboard, what happens to the LED's when you flip the switch? What do you think is happening? Which circuit is keeping the LED on the longest?
Look at the schematic diagram. When the switch is up, the capacitors are being charged up. Once you flip the switch down, the capacitors release the charge and the LED will light up. The LED will slowly die out as the charge runs out. If you are unsure about why one circuit holds a larger charge than the other, then read over "Circuit Concepts"
