How about this? Assign an electronic component to each character that reflects their attitudes and behaviors. Just as a fun way to decide how a character will react.
| Resistors: The device resists the flow of current. |
| Capacitors: These components can store electric charge temporarily. |
| Diodes: Diodes allow electric current to flow in a single direction only. Each diode has two terminals known as the anode and cathode. When the anode is charged with positive voltage and the cathode with a negative one, electric current can flow. Reversing these voltages will prevent the current from flowing. |
| Transistors: These components have three terminals. For the components to work, voltage has to be applied to one of them; the base terminal. The base can then control current flow in the two other terminals (the emitter and collector). |
| Inductors: These are passive components that store energy in form of a magnetic field. |
| Integrated Circuits: An integrated circuit refers to a special device that has all the components required in an electronic circuit. |
| Microcontrollers: Microcontrollers are small computers used to control a multitude of devices. |
| Transformers: Built with two coils of wire, transformers are commonly used to step up or step down power. |
| Batteries: Batteries convert chemical energy to electrical energy. The two different cells of a battery are anode (+) and cathode (-). |
| Fuses: Fuses help preserve components from overloading with excessive current. |
| Relays: These electromechanical switches shut power on or off. |
| Switches: Switches interrupt current. |
| Motors: Motors convert electrical energy into mechanical energy. |
| Speakers: Electrodynamic coils attached to a diaphragm that convert changing electrical impulses into sound waves. A microphone can be made the exact same way but converts sounds into electricity. |
