Why width of collector is high?

In most transistors, the collector region is made physically larger than the emitter region because it has to dissipate much greater power.

Which has greater width in transistor?

Collector region of a transistor is highly doped so collector region has more width than other two.

Why is the base of a transistor made thin as compared to emitter and collector?

In a transistor, the base is made extermely thin to reduce the combinations of holes and electrons. Under this conditions, most of the holes (or electrons) arriving from the emitter diffuses across base and reach the collector. This is the main reason that power gain and voltage gain are obtained by a transistor.

Is the base region much thinner or much wider than the collector and emitter regions?

Transistors have three sections namely – the emitter, the base, and the collector. The base is much thinner than the emitter, and the collector is comparatively wider than both. The emitter is heavily doped so that it can inject large number of charge carriers for current conduction.

Why collector width is made larger than emitter and base width is smaller than other regions?

Collector is made physically larger than emitter and base because collector is to dissipate much power.

Why is the collector made larger than the emitter and the base also why is emitter the most heavily doped?

In most transistors, emitter is heavily doped. Its job is to emit or inject electrons into the base. The collector is so named because it collects electrons from base. The collector is the largest of the three regions; it must dissipate more heat than the emitter or base.

Why is Collector current slightly less than emitter current?

The base contains more holes than electrons. As the direction of current is opposite to the flow of electrons we can understand that current from the emitter is conducted to the base and the collector. Hence, the collector current will always be slightly less than the emitter current.

Why collector current is more than base current?

Answer: Explanation: Base is much narrower and thinner than collectors,hence the majority of charge carriers are received by collector. Hence,collector current is greater than base current.

Why the collector is made larger that the emitter and base also why the base region has the smallest width?

Why collector is made larger than emitter and base? Collector is made physically larger than emitter and base because collector is to dissipate much power.

Why the thickness of base is smaller than emitter and collector?

The base region in a transistor is made very thin so that there is a better conduction of majority carriers from emitter to collector through base. The base region in a transistor is doped lightly so that the number density of majority carriers (electrons in p-n and holes in n-p-n transistor) is low.

Why the width of the base region of a transistor is kept very small compared to other regions?

Why the width of the base region of a transistor is kept very small compared to other regions? Base region of a transistor is kept very small and very lightly doped so as to pass most of the injected charge carriers to the collector.

When the collector junction in a transistor has?

In CE transistor amplifier, the collector junction has bias and emitter junction has bias.
