Question

For a transistor, in a common emitter arrangement, the alternating current gain $\beta$ is given by

✓

Answer

(a) $\beta=\frac{\Delta I_{c}}{\Delta I_{b}}$

Beta is the transistors forward current gain in the common emitter configuration. Beta has no units as it is a fixed ratio of the two currents, $I_{c}$ and $I_{b}$ so a small change in the Base current will cause a large change in the Collector current.
