Question

The collector current (IC) that is obtained in a collector to base biased transistor is_________

(a) (VCC-VBE)/RB

(b) (VCC+VBE)/RB

(c) (VCE-VBE)/RB

(d) (VCE+VBE)/RB

This question was posed to me in homework.

The query is from Collector-to-Base Bias topic in chapter Transistor Biasing and Thermal Stabilization of Electronic Devices & Circuits

Answer 1

The correct choice is (a) (VCC-VBE)/RB

To explain: The collector current is analysed by the DC analysis of a transistor. It involves the DC equivalent circuit of a transistor. The base current is first found and the collector current is obtained from the relation, IC=IBβ.
