For common-emitter configuration of n-p-n transistor, the current gain β is given by:
Correct answer: A. IC/IB
- A. IC/IB
- B. IC/IE
- C. IE/IB
- D. IB/IE
Explanation
This is the correct answer. The current gain (β) for a common-emitter configuration of an n-p-n transistor is defined as the ratio of the collector current (IC) to the base current (IB). It represents how much the collector current is amplified with respect to the base current.

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
