Offering a high i/p impedance & a low o/p impedance are commonly used as a buffer.The voltage gain of this transistor is unity, the current gain is high and the o/p The common collector transistor configuration is also known as the emitter follower because the emitter voltage of this transistor follows the base terminal of the transistor. Then to summarise, this type of bipolar transistor configuration has a greater input impedance, current and power Ic" is the current flowing into the collector terminal, "Ib" is the current flowing into the base terminal and "Ie" is the current flowing out of the emitter terminal. The collector current is controlled by the base current (and so, indirectly, the base to emitter voltage using an exponential relationship) the collector voltage (if above a few volts it has only a little effect), and A transistor is made up of two PN junctions, an emitter junction and a collector junction. Hello, The base current controls the collector current when the transistor is in the active region. Why does collector current increase with base current in BJT?.
For example, Table 1 shows the h FE specification for the 2SC2712. Note, however, that h FE varies with the collector-emitter voltage (V CE). Generally, the current that flows from the emitter to the collector or vice versa is the base current times the DC current gain (h FE). Now, the base current is the sum of the 2 transistors base current, but the collector current, is the difference of the 2 transistors collector current.From these, you can calculate the base current I B = 9 V − 0.6 V 220 k Ω and collector current I C = 9 V − 0.2 V − 3 V 330 Ω, and then find β = I C I B. Assuming the LED is white, its V F is about 3V. The transistor is in saturation, so that its V C E is about 0.2V. Conventional current direction in npn transistor Consider the npn transistor as shown in the below figure. On the other hand, the base current (IB) and collector current (IC) are flowing outwards the transistor. The emitter current (IE) direction which is represented by an arrow shows that the emitter current is flowing into the transistor. And it all depends on what information is already known about the transistor: 1st Way To Calculate Base Current I B. There are several ways to find the base current, IB, of a transistor. Without this base current, the transistor can't turn on. The base current, IB, of a transistor is a crucial current of a bipolar junction transistor.

How to Calculate the Base Current of a Transistor.And it all depends on what information is already known about the transistor: 1st Way to Calculate Collector Current Ic There are several ways to find the collector current, Ic, of a transistor. The collector current, Ic, of a transistor is the amplified output current of a bipolar junction transistor.
