The output characteristics of an $n-p-n$ transistor represent, ($I_C =$ collector current, $V_{CE} =$ potential difference between collector and emitter, $I_B =$ base current, $V_{BB} =$ voltage given to base, $V_{BE} =$ the potential difference between base and emitter)
- Achanges in $I_C$ as $I_B$ and $V_{BB}$ are changed
- Bchanges in $I_C$ with changes in $V_{CE}$ ($I_B =$ constant)
- Cchanges in $I_B$ with changes in $V_{CE}$
- Dchange in $I_C$ as $V_{BE}$ is changed
