- $V^{out}$ is the voltage we want to control: it will be high when the transistor is in the 'on' state and low otherwise

We recall that voltage is the potential difference between two points or terminals in a circuit. High voltage increases the flow of current, low voltage restricts or reduces it.

When the voltage at the base is high a current flows from the collector to the emitter and the transistor is "on".
