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.

*need a resistor on the end of every CAN bus

Pulse-width modulation (PWM) (don't use that anymore) - a method of controlling the average power or amplitude delivered by an electrical signal. Used to control the output of motors not using the CAN bus 

Wire Gauges - Indicates the size of wires

  • Smaller gauge (smaller number)
    • Larger size
    • Lower electrical resistance
    • Greater load-carrying capacity
  • We usually use:
    • 2, 4 - battery
    • 8, 10, 12 - Krakens
    • 18, 22 - sensors
