Normally, the value of collector current is given by This means that the collector current will be amplified by 80 times than that of the base current.Īnother current that we've brought into consideration is the emitter current (IE), but due to transistor action we assume that the value of Emitter current is almost equal to Collector current, however the difference between the both can be found with the value of α. This amplification depends on the amplification factor (hfe) which is 80 for 2N5551. Changing the value of RL will affect the amplification of the output wave.Ī transistor is normally a current amplifier, meaning the current flowing though the base will be amplified in the current flowing through the collector. The Resistor R1 is the load resistor and the resistor R2 is the emitter resistor. In the above circuit the resistors R3 and R4 form a potential divider which decides the Emitter -Base voltage (VBE). Here the input sine wave of magnitude 8mV (yellow colour) is amplified to 50mV (Pink colour) as shown in the graph. The simulation graph that shows the amplified output sine wave can also be found. A very simple bare minimum circuit for a transistor to work as an amplifier is shown below. The 2N5551 NPN transistor is widely used for amplification.
