Question

Define trans conductance of a transistor.

✓

Answer

The trans conductance of a transistor is defined as the ratio of the change in collector current to the change in base voltage at constant collector voltage.
$\text{gm}=\Big(\frac{\Delta\text{I}_\text{C}}{\Delta\text{V}_\text{b}}\Big)_{\text{V}_\text{C}=\text{Cons}\tan\text{t}}$
