What is a transistor that is normally on with no applied signal?

The PNP transistors conducts when there is no signal at base (0V or grounded), when base current is increased the conduction of PNP transistor decreases.


What is the mean of pnp low freequency transistors?

There are two basic types of bipolar transistors. One being the NPN and the other, the PNP. In your situation, you're dealing with a PNP transistor, that requires a negative going voltage on the base connection to make it function. Without going into all the details, there are several ways in which this transistor can be utilized. The low frequency refers to the frequency range in which a transistor will function. The low frequencies could be for audio, power regulation or several other applications where dealing with signals in the higher frequency ranges aren't necessary, such as radio frequencies.


Why same h parameter model is used for npn and pnp transistor?

The same h parameter model is used for npn and pnp transistors because gain is gain. It does not matter if you are using a negative or a positive system. So long as you are consistent in your calculations, you will get the correct results. In an NPN transistor operating in class A, if you increase the base current by increasing the base voltage, you will increase the collector current which decreases the collector voltage. In a PNP transistor operating in class A, if you increase the base current by decreasing the base voltage, you will still increase the collector current, which will increase the collector voltage.

What is the pnp switch circuit?

The PNP switch circuit uses a PNP transistor to control the flow of current based on the input signal. When the input signal is high, the transistor allows current to flow from the collector to the emitter, turning the switch "on". When the signal is low, the transistor blocks current flow, turning the switch "off".


Is BT169 a npn or pnp transistor?

BT169 is neither an NPN nor a PNP transistor. BT169 is a thyristor, otherwise known as a silicon controlled rectifier.


When a PNP transistor is connected in a circuit it can be used as a power amplifier because?

A PNP transistor has no advantage or disadvantage over an NPN transistor in its ability as an amplifier. Rather, the current-handling capacities of the transistor determine if it's usable as an amplifier.

How do you know if a transistor is a PNP or an NPN?

To know if a transistor is PNP or an NPN,the following should be verified:For a PNP transistor, the base-collector junction is forward biased while the base-emitter junction is reversed biased.For an NPN transistor, the base-emitter junction is forward biased while the base -collector junction is reversed biased.
