in pnp transistor after some time on increasing voltage why the current become constant ?
which voltage you are talking about? if it is base voltage then it might be follows.XuFyaN said:in pnp transistor after some time on increasing voltage why the current become constant ?
In a Pnp transistor, the voltage and current relationship is opposite to that of an Npn transistor. This means that in a Pnp transistor, a negative voltage applied to the base will allow a higher current to flow from collector to emitter.
A Pnp transistor voltage/current graph is used to visualize and analyze the behavior of a Pnp transistor under different voltage and current conditions. It helps in understanding the amplification and switching capabilities of the transistor and is an important tool in transistor circuit design.
The Pnp transistor voltage/current graph is different from an Npn transistor graph in terms of the direction of the voltage and current scales. In a Pnp transistor graph, the voltage scale is negative, and the current scale is positive, whereas in an Npn transistor graph, both scales are positive.
The shape of the Pnp transistor voltage/current graph is affected by various factors such as the type of material used in the transistor, the doping levels of the different regions, the temperature, and the external biasing voltages applied to the transistor.
The Pnp transistor voltage/current graph can be used to determine the stability of a circuit by analyzing the operating points of the transistor. If the operating points lie within the active region of the graph, the circuit is considered stable. However, if the operating points lie in the saturation or cutoff regions, the circuit may become unstable and may not function properly.
