Can base current be more than collector current?

Can base current be more than collector current?

All Answers (25) Hello, an increase in base current means more bias to the transistor which further means collector current will also increase but till the limiting value of the transistor parameters. A transistor is made up of two PN junctions, an emitter junction and a collector junction.

Is the base current and collector current are approximately equal?

In a BJT, the collector current is approximately equal to the base current. The voltage gain of a transistor is inversely proportional to the change in output current.

How is the base current and collector current related?

The base current and collector current combine and become the emitter current. But since the base current is anywhere from 1/20 to 1/300 of the collector current, emitter current is only very slightly greater than collector current.

Why is base current equal to emitter current?

We already know Emitter Current is equal to sum of base and collector current. Now current in base is generated when electrons from emitter region combing with holes in base region. Since base is very weak and has only a few number of holes. These holes combing with electron and generate a little amount of current.

What causes a DC collector to drop out of phase?

The collector current flows through a collector resistor R C connected between the collector and a DC power supply, producing a voltage drop across R C. This action causes the collector voltage to drop as the voltage applied to the base increases, thereby producing an output voltage that is 180 degrees out-of-phase with the input voltage.

When do e-electrons leave the emitter they leave the collector?

In CE & in All cases, in an NPN configuration, Electrons leave Emitter enter Base, Then leave base – Enter collector, then leave Collector, and then enter emitter to complete the path Therefore, for E – Electrons Entering, For Base & Collector Electrons leaving
