Question

You know properly biased npn transistor most of the electrons from the emitter

Answer 1

4. In a properly biased N-P-N transistor , most of the electrons from the emitterbecause they pass to the collector through the base

Answer 2

If an NPN transistor is properly biased in the active region, then most of the electrons from the emitter pass through the base to the collector.

Explanation:

• We know that the base emitter junction of an NPN BJT in the active region will be forward biased, while the collector base junction will be reversed biased
• The emitter region of an NPN transistor is heavily doped(n++) so that the diffusion current primarily consists of free electrons moving from the emitter into the base
• Electrons flow into the emitter.
• Holes flow out of the emitter.
• Holes flow into the collector
