Is emitter current the sum of collector current and base current?

The emitter current is equal to the sum of base current and collector current.

Is collector current equal to emitter current?

The common emitter configuration has a current gain approximately equal to the β value of the transistor itself. However in the common collector configuration, the load resistance is connected in series with the emitter terminal so its current is equal to that of the emitter current.

What is the relationship between the collector and base current?

The base current controls the collector current when the transistor is in the active region. A transistor is made up of two PN junctions, an emitter junction and a collector junction. The active region is when the emitter junction is forward biased and the collector junction is reverse biased.

Is emitter current greater than collector current?

We know that the concentration of the impurities in the collector is slightly less than the concentration in the emitter. Hence, even if you apply the battery at the junction of the collector and the base in forward bias, the emitter current will always be greater than the collector current.

What is emitter base and collector?

The base is the gate controller device for the larger electrical supply. The collector is the larger electrical supply, and the emitter is the outlet for that supply. By sending varying levels of current from the base, the amount of current flowing through the gate from the collector may be regulated.

What is difference between base-emitter and collector?

Also note that the collector voltage is higher than the base voltage. The main differences between emitter and collector are doping concentration and size. The emitter is heavily doped, while the collector is lightly doped. You could try to swap them, but you’ll get a very low HFE, probably even less than 1.
