In a transistor amplifier, each branch (base, collector, emitter) carries a current composed of:
Total Current = DC bias current + AC signal current
- The DC component is required to bias the transistor and set its operating point (Q-point).
- The AC component represents the input signal that gets amplified.
This combined current ensures linear amplification without distortion, provided the transistor remains in its active region.
So, during normal amplifier operation, the current is a sum of AC and DC components, not one or the other alone.
