PNP
The other kind of BJT is the PNP with the letters "P" and "N" standing for the majority charge carriers inside the dissimilar regions of the transistor.
Figure: The symbol of a PNP Bipolar Junction Transistor.
PNP transistors contain a layer of N-doped semiconductor among the two layers of P-doped material. A small current that is leaving the base in common-emitter mode is amplified in the collector output. In other words, a PNP transistor is "on" while its base is pulled low relative to the emitter.
The arrow (shown in figure) in the PNP transistor symbol is on the emitter leg and points in the direction of the conventional current flow while the device is in forward active mode.
One mnemonic device for making out the symbol for the PNP transistor is "pointing in proudly / 'pointing in - pah'."
With neat diagrams explain the configuration of a step-by-step switching system. Schematic diagram for such an exchange is given in Figure. Every subscriber is connected to a
Determine the response of a series R-C circuit to a SQUARE wave. Explain how the time constant affects the waveform observed across the components. Illustrate your answer by means
In real life, transformers have losses which cause their behaviour to deviate from the ideal. Explain the reasons for this non-ideal behaviour
Q. Define Number Systems? A number system, in general, is an ordered set of symbols (digits) with relationships defined for addition, subtraction, multiplication, and division.
Lead Acid Accumulators : These are the most common storage batteries which can deliver a heavy current when short-circuited. There are also many other hazards with these accumulat
What is meant by Daisy Chaining method? It does not need any priority resolving network, rather the priorities of all the devices are effectively assumed to be in sequence.
Q. Two shunt wound generators running in parallel supply a total load current of 4000 A. Each generator has an armature resistance of 0.02? and a field of 40?. The fiels are exci
Q. Explain working of Public Switched Telephone Network? Public Switched Telephone Network (PSTN) accommodates two kinds of subscribers: private andpublic. Subscribers to priv
Usage of transistor: The bipolar junction transistor that is abbreviated as BJT was the most generally used transistor in the 1960s and 70s. Even later than MOSFETs became ext
