Circuit - the route electrons can flow along
Voltage - pushing force of electrons on a circuit; the more voltage, the more potential energy.
Current - flow of electrons, measured in Amps, the larger the amperage, the more electricity can flow through the circuit
Resistance - restriction to the flow of electrons, measured in Ohms. The longer and thinner the wire, the greater the resistance
CAN bus - a message-based protocol that allows devices on the CAN bus to communicate with each other.
Resistors - restricts the flow of electrons, protects components from too much electrons flowing through it.
