Volts (Power), VV:
The potential difference in charge between two points
The size of the force that sends the electrons through a circuit
Amperes (Current), Amp, I
The unit used to measure electric current
The number of electrons flowing through a circuit.
Watts, W
A measure of the rate of energy transfer of an appliance
The rate of energy generated or consumed
Ohms (Resistance), 𝝮
A measure of the opposition to current flow in an electrical circuit
Circuit:
Circuit:
A closed loop of conductive material.
Continuous flow of electric current. Positive to negative or ground. (+, -)
Series:
Series:
Components are chained together from positive to negative to positive, etc.
Parallel:
Parallel:
Negative to Negative and Positive to Positive
CANchain:
CANchain -
The chain of CAN devices and their connections gives information to each other. Also referred to as CAN bus, there may be multiple for different parts of a robot.
Electrically, the FRC CAN network is a two-wire bus, designed to allow dozens of devices to talk to each other with a single network.
Needs two 120-ohm resistors to terminate the ends of the bus.
