How do you calculate the current gain of a transistor?
Bipolar transistor current gain is also called "Beta," or the h-parameter "hfe." beta = current_out / current_in The beta of a BJT is mostly determined by the thickness of the Base region, and by the excess doping in the Emitter relative to the Base. A thin Base and a heavily-doped Emitter leads to a high value for current gain. In a BJT, beta = Ic / Ib In a FET, beta is usually taken as infinity, since no current flows in or out of the gate. Beta is an impirical number. It means nothing unless the Ic is known or the load. It can have a beta from 1000 to 10 it all depends on the load.

How is the relationship between protons and alpha particles similar to the relationship between beta particles and electrons?
An Alpha Particle is a fast, bare Helium nuclei composed of two protons, two neutrons, and no electrons, that is ejected at high velocity from a decaying nuclei. A Beta Particle is an electron or positron, ejected at extremely high velocity from a decaying nuclei. Both alpha particles and protons are Bosons. Both beta particles and electrons are Leptons. Their relationships are similar because the electron and proton are both components of atoms. The beta and alpha particles are both fragments ejected from decaying atoms.
Why gain increases in low frequency region in BJT?
Because Beta (current gain) in a transistor is inversely proportional to frequency. Hence it increases as frequency decreases. Also the ac voltage gain is directly proportional to Beta.
What is Sigma Nu's motto?
The motto of Nu Alpha Nu is 'Death Before Dishonor'.
When the forward saturation in Bipolar junction transistor occurs?
Forward saturation in a BJT occurs when the ratio of collecter-emitter current and base-emitter current reaches hFe or dc beta. A that point, the BJT is no longer operating in linear mode.
What is the alpha of the bipolar junction transistor?
The change of collector current with respect to emitter current. Typically 0.95 to 0.995. So a transistor with alpha of 0.95 might have an emitter current of 10 mA, collector current 9.5 mA. The "missing" current becomes base current and does not reach the collector. The more commonly used figure for current gain is beta, the ratio of collector current to base current, typically 50 to 500. In CB MODE It is called the common base, short-ckt, amplification factor.
When was Alpha Beta created?
Alpha Beta Alpha was created on 1950-05-03.
When did Alpha Beta end?
Alpha Beta ended in 1995.
What is the percentage of alpha and beta in an equimolar mixture of alpha d glucose and beta d glucose?
64% of Beta and 36% of alpha.
What comes after alpha?
After alpha comes beta in the Greek alphabet.
When was Alpha Beta Gamma created?
Alpha Beta Gamma was created in 1970.
When was Beta Phi Alpha created?
Beta Phi Alpha was created in 1919.
What is a another name for the stars called alpha and beta?
There is no single star called "alpha" or "beta". The brightest stars (usually) in each constellation are called "alpha" and "beta", followed by the Latin genitiv of the constellation; for example, "alpha centauri", "beta centauri", "alpha orionis", "alpha cruxis", etc.
Why are alpha and beta rays bent in different directions?
Alpha and beta rays are bent in different directions because alpha is positively charged, beta is negative.
Is bacillus subtilis a beta or alpha hemolysis?
is bacillus subtilis beta or alpha hemolysis
A PNP transistor is connected in a circuit so that the collector-base junction remains reverse biased and the emitter-base junction is forward biased This transistor can be used as a power amplifi?
No freaking way but it would make an excellent low level switch if forced at beta of 10
