No. The PNP or NPN of a transistor refers to the doping or impurities introduced to the silicon during manufacturing, and changes the polarity of the supply voltage to each pin. In a vacuum tube, the anode is always positive, the cathode is always negative. The control grid can vary between more negative than the cathode to cut off current flow, up to equal to the potential of the cathode, at which point the tube is saturated, or at full current. There is no 'reverse polarity' tube to correspond with the two types of transistor.

How many vacuum tube in one transistor?
There are no vacuum tubes in a transistor. A vacuum tube is an electronic device that uses a heated cathode in a vacuum to direct and control an electron stream to an anode, also known as the plate. The vacuum tube is old technology, but it is still used today, typically in high power applications such as transmitters. A transistor is an electronic device that uses solid-state semiconductors to similarly control an electron stream. The transistor is newer than the vacuum tube. It offers lower power, smaller size, easier use and other enhancements over vacuum tubes, within limits, of course, such as voltage and power.
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.
Which is the largest current in a pnp transistor?
emitter current
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.
What is the role of pnp and military?
PNP Positive Negative Positive, is a type of Transistor. I don"t know of military applications.
What computer component did the transistor replace?
the vacuum tube
What are the Similar transistor for 221334 PNP transistor?
Similar to a 2N3906 PNP transistor
What replaced the vacuum tube?
The transistor replaced the vacuum tube, allowing radios to get much smaller and portable.
What electronic component is a gate or switch for electrical signals?
Transistor or vacuum tube.
What invention replaced the vacuum tube?
The answer to the question is TRANSISTER
What is a vacuum tube used for?
The same things a transistor is used for.
What are the functions and empowerment of PNP as per PNP laws?
pnp and npn transistor

Is a vacuum tube far more stable than a transistor?
yes but vacuum tubes produce more sperm trololol
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.
What characteristics made the transistor better than the vacuum tube?
There were obvious differences between the trasisitor and the vacum tube. The transistor was faster, more reliable, smaller, and much cheaper to build than a vacuum tube. One transmisor was the equivalent 40 vacuum tubes. They also didn't produce heat compare it to a vacuum tubes. Conduct electricity faster and better than vacuum tubes.
