What is the value of collector resistance?

The collector current only varies about 0.4 mA as the collector resistance, R1, goes from 100Ω to 3kΩ, causing the collector voltage to go from about 19.6V to 10.3V. The equivalent transistor collector resistance is thus about 22kΩ. if Rc value limit the current below the Ic.

Which has more resistance emitter or collector?

as we know emitter is heavily doped and it has the highest resistance as compared to collector,so we have to employ trial and error method to detect BASE,EMITTER and COLLECTOR TERMINALS!!!

What is the collector current when the base resistance is open?

If the base resistance is open, there is no path to flow the current from the source to the base of the transistor. Hence, the base current is 0 Amps.

What is the difference between base emitter and collector?

The emitter-base circuit is in forward biased and offered the low resistance to the circuit. The collector-base junction is in reverse bias and offers the higher resistance to the circuit. The base of the transistor is lightly doped and very thin due to which it offers the majority charge carrier to the base.

What is a collector resistance?

The purpose of the collector resistor Rc is to set the collector current Ic as well as the emitter- collector voltage Vce. In other words, Rc helps to set the transistor at the “operating point” of the ampli- fier. The purpose of the emitter resistor Re is to prevent “thermal runaway”.

How transistor detect emitter base collector?

In plastic casing, one side of the transistor is Flat which is the front side and the pins are arranged serially. To identify the pins, keep the front flat side facing you and count the pins as one, two etc. In most NPN transistors it will be 1 (Collector), 2 (Base) and 3 ( Emitter ). Thus CBE.

Is collector more doped than base?

The doping level of collector is intermediate between the heavy doping of emitter and the light doping of 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.
