text: β linearly relates the collector current (I C ) to the base current (I B ):
text: Since the electrical relationship between these three currents, Ib, Ic and Ie is determined by the physical construction of the transistor itself, any small change in the base current ( Ib ), will result in a much larger change in the collector current ( Ic ).
text: The arrowhead shows the conventional direction of Collector current (I C ), Base current (I B ) and Emitter current (I E ).
text: To bias a transistor we have to supply current to base pin, this current (I B ) should be limited to 5mA.
text: To bias a transistor we have to supply current to base pin, this current (I B ) should be limited to 5mA.
text: Therefore the current through RB is I B = (
text: Due to which only a few electrons are combined and remaining constitutes the base current I B .
text: The base current, I B , of a transistor is a crucial current of a bipolar junction transistor.
text: Now we can calculate the value of the base current, I B , in the circuit:
text: If the base current I B , falls to 0, the transistor enters the cutoff region and shuts off.
text: Output characteristics for CE mode is the curve or graph between collector current (I C ) and collector – emitter voltage (V CE ) when the base current I B is the parameter.
text: As the base current I B = 0, It acts as an open circuited.
text: As V cc is of fixed value, on selection of R b , the base current I b is fixed.
text: Hence, the base current I b {\displaystyle I_{\text{b}}} is
text: A lower base-resistor voltage drop reduces the base current I b {\displaystyle I_{\text{b}}} , which results in less collector current I c {\displaystyle I_{\text{c}}} .
text: However, this only happens when a small biasing current ( Ib ) is flowing into the base terminal of the transistor at the same time thus allowing the Base to act as a sort of current control input.
text: To bias a transistor we have to supply current to base pin, this current (IB) should be limited to 5mA.
text: To bias a transistor we have to supply current to base pin, this current (IB) should be limited to 1/10th of the collector current and voltage across the base emitter pin should be 5V maximum.
text: However, if it is not given, it can be calculated if the currents, Ib (the base current) and either Ie ( the emitter current) or Ic (the collector current) are known.
text: and instead it is almost entirely controlled by the base current, Ib.
