Question A-002-003-002

Which component conducts electricity from a negative emitter to a positive collector when its base voltage is made positive?

Correct Answer

An NPN transistor

Explanation

In an NPN transistor, a positive voltage on the base (relative to the emitter) forward-biases the base-emitter junction, allowing electron flow from the N-type emitter to the N-type collector.
