WebApr 9, 2024 · In standard operation the BJT transistor works as an amplifier. Let’s apply to the base AC signal and DC signal and we will see the amplification on the resulting I C – V E C curve, so all oscillations of the base current is resulting in amplified collector current. Important point to consider is self-biased BJT circuit, that is depicted below. WebMar 19, 2024 · Transistors may be used as switching elements to control DC power to a load. The switched (controlled) current goes between emitter and collector; the controlling current goes between emitter and base. When a transistor has zero current through it, it is said to be in a state of cutoff (fully nonconducting).
