| A | B |
| Wiring Diagram | shows actual connections in picture form to demonstrate how to set up a circuit |
| Circuit | uninterrupted connection or loop of electricity from voltage source to ground |
| Current | rate of charge flow, measured in Ampere |
| Schematic | a visual symbolic plan for a circuit, different from a wiring diagram that shows the actual connections, a schematic shows what is connected to what in symbols |
| Ohm’s Law | relationship between Voltage, Current, and Resistance: V=I*R |
| Resistor | a component that opposes and reduces current |
| Resistance | opposition to charge flow, measured in Ohms |
| Power Bus | on a breadboard, there are long lines of connections on either side - it is typical to connect the constant voltage and ground to these |
| Voltage | electrical potential, measured in Volts |
| Breadboard-solderless breadboard | a system for making temporary wired connections to test circuits |
