What else can I help you with?
The life of an electronic transistor is normally distributed with a mean of 500 hours and a standard deviation of 80 hours determine the probability that a transistor will last for more than 400 hours?
z score = (400-500)/80=-1.25 probability under curve to right of -1.25 = .8944
What circumstances led to the invention of the transistor in 1947?
before the invention of transistor,thyristor was used instead of transistor but thyristor produces more heat in the circuit and size is more when compared to transistor
Different between power transistor and transistor that used in small signal?
Power transistor can conduct large amount of currents through it, more than small signal transistor. power transistor has a vertical structure and small signal transistor has horizontal structure.In power transistor quasi saturation region is present which is absent in the small signal transistor. In power transistor there is a inculsion of drift layer which is not there in the small signal transistor. Power dissipation is less in power transistor and it is more in small signal transistor. b.v.polytechnic,vasai pushkar vaity.
What is composite transistor?
A Darlington transistor is a composite transistor. The definition is a combination of two or more transistors that have the purpose of increasing the current gain.
What is the minimum voltage required to turn on a pnp transistor?
If it's a germanium transistor, 0.3 volts. If it's the more common silicon transistor, slightly more than 0.6 volts.
How long can the iPad's battery last?
. The iPad can last 15 hours or more
Why CE transistor is more temperature senstive than CB transistor?
In CE transistor volteage divider biasing is used, which is independent of temperature and other parameters.
Who was the transistor invented for?
The transistor is a replacement for vacuum tubes, which is smaller, cheaper, and more reliable for most purposes.
Which is the best ic or transistor amplifier for good sound quality?
Smooth clear sound comes from IC and transitor has more loudness and more bass and also consumes more electricity , transistor is good for outdoor used but if u love more loudness then try transistor
What song includes the words transistor radio in it?
Here are some songs with transistor radio in the title and there are probably many more: Transistor Sister by Freddy Cannon Twisted Transistor by Korn Transistor Radio ... three songs by Cloud Cult, Jaya the Cat, and The Methadones Tiny Blue Transistor Radio by Connie Smith
Can drug cleansers last more than 5 hours?
Yeah than can last more than 5 hours unless it's being used to much of it and they can last up to a week or two believe or not.
What is emitter biasing?
Emitter biasing is when you add a resistor between the emitter of a transistor and the 0v rail so that any voltage developed across the emitter will subtract from the voltage on the base and effectively turn the transistor OFF. We are talking about an NPN transistor and the transistor is an "ordinary transistor" or BJT (bi-polar Junction Transistor). For more information on transistor biasing see: Talking Electronics website.
