Which one of the following relation is true for a transistor?
Correct answer: C. Ia=Ic/Ig
- A. Ie=Ic-Ib
- B. Ie=Ia-Ic
- C. Ia=Ic/Ig
- D. β =Ib/Ie
Explanation
The explanation is given below: Ia = Ic / Ig represents the relationship between the collector current (Ic) and the total input current (Ig) in the context of a transistor, where Ia is an amplification factor. Ia represents amplification factor or common-base current gain. Ic represents collector current. Ig represents total input current. In common base configuration of a bipolar junction transistor, this relationship describes the current gain. The collector current is determined by the total input current, which includes the base current and the collector current. This equation is specific to the common-base configuration of a BJT and provides a way to quantify the transistor's amplification of the input current.The common base configuration is most widely used than common emitter or common collector configurations.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
