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