# Circuit Basics
|
||||
|
||||
## Current
|
||||
|
||||
Current is the flow of charge through a circuit. Conventionally we
|
||||
think of this as happening from $+$ to $-$ of the power supply of the
|
||||
circuit.
|
||||
|
||||
## Voltage / Potential / Resistance
|
||||
|
||||
Voltage is how fast the current can move in the circuit. River
|
||||
metaphor:
|
||||
|
||||
- current = flow rate: ($\si{\liter\per\second}$)
|
||||
- voltage = change in height: ($\si{\meter}$)
|
||||
|
||||
Other devices in a circuit can impede / effect current flow. We'll
|
||||
call them resistance(s).
