Series Circuits A series circuit only allows one path for the electricity to flow through. Note that the dough acts as a resistor and a wire, therefore the resistor as show in the schematic are not needed. A LED only works in one direction. Make sure the longer wire or lead is towards the positive (red) side. Also, never directly connect and LED to a voltage source (battery) because it will burn out. Battery LED #1 LED #2 LED #3 Series Circuits LEDs can be added however they will get more dim because there is less electricity available to power them. If one of the LEDs is taken out, the entire circuit is broken and all of the lights will go out. Parallel Circuits A parallel circuit allows multiple paths for electricity to flow through. Also note that the dough acts as a resistor and a wire, therefore the resistors as show in the schematic are not needed. A LED only works in one direction. Make sure the longer wire or lead is towards the positive (red) side. Also, never directly connect and LED to a voltage source (battery) because it will burn out. LED #1 Battery LED #2 LED #3 !"#"$$%$&'(#)*(+, LEDs or other electrical items are connected to the dough each in their own loop or circuit. Since electricity flows through each LED independently, if one is removed or burns out, the others will continue to shine brightly.
