Question:

In a n-p-n transistor –

Options:

holes moves from emitter to base

holes move from base to collector

negative charge moves from emitter to base

negative charge moves from collector to base

Correct Answer:

negative charge moves from emitter to base

Explanation:

In n-p-n transistor current flows form base to emitter. Therefore in n-p-n transistor negative charge moves from emitter to base
