If the beta (β) of a bipolar junction transistor (BJT) increases with temperature, it can lead to enhanced current gain, resulting in greater amplification of the input signal. However, this increase in beta can also cause thermal instability, as a rise in temperature can lead to higher leakage currents, potentially driving the transistor into saturation. Additionally, increased beta may exacerbate thermal runaway conditions, where rising temperatures lead to even higher currents and further temperature increases, risking device failure. Proper thermal management and biasing techniques are essential to mitigate these effects.
What else can I help you with?
What kind of radiation increases the atomic number of the donating atom by one Alpha Beta Gamma or Neutron?
Neutron radiation increases the atomic number of the donating atom by one. This occurs when a neutron is absorbed by an atom, causing it to become unstable and undergo beta decay, which results in an increase in atomic number.
Does the beta particle increase or decrase mass?
The beta particle decreases mass because it is an electron emitted from a nucleus during beta decay. The process of emitting a beta particle can result in the conversion of a neutron into a proton, leading to a decrease in the mass number of the nucleus.
When did The Tail of Beta Lyrae happen?
The Tail of Beta Lyrae happened in 1983.
What is the temperature of Beta Phoenicis?
Its surface temperature is 4950 K.
What is the temperature of Aquarius beta?
Beta Aquarii has a temperature of 5,700 Kelvins equal to 9800.33° F or 5426.85° C.

Does transistor current gain increase or decrease with temperature?
In general, transistor current gain (beta) increases by approximately 0.7% per degree centigrade above room temperature. The current gain of a heated device may be found according to: beta(T) = beta(25 degrees C)*(1+0.007(T-25)) This is why robust circuits are designed such that there is no dependence on beta.
What is the advantage of WACC?
All else equal, the weighted average cost of capital (WACC) of a firm increases as the beta and rate of return on equity increases, as an increase in WACC notes a decrease in valuation and a higher risk.
When beta particle is ejected from a nucleus does it have a greater mass or charge?
The beta particle is formed when a neutron decays into a proton and electron. So the number of protons increases, causing an increase in the charge of the nucleus by 1, and a very tiny decrease in mass.
When a radioactive isotope emits a its atomic number increases?
When a radioactive isotope emits a beta particle (high-energy electron), a neutron in the nucleus is converted into a proton. This causes the atomic number of the nucleus to increase by one because a proton has a positive charge and changes a neutron to a proton increases the atomic number.
What will happen to the expected return on a stock with a beta of 1.5 and a market risk premium of 9 percent if the Treasury bill yield increases from 3 percent to 5 percent?
2.0%
If portfolio a has a beta of 1.5 and portfolio z has a beta of -1.5 what do the two values indicate?
Simple scenario: Taking into account beta of index is set at 1.0; Lets say market increases by 5% Beta of 1.5 would indicate that the particular portfolio would increase by 7.5% as for beta of -1.5, the portfolio would decrease by 7.5% Beta is a measure of sensitivity of market base on the reference index. Negative beta would mean that the portfolio is inversely proportional to market performance.
Does the beta particle increase or decrase mass?
The beta particle decreases mass because it is an electron emitted from a nucleus during beta decay. The process of emitting a beta particle can result in the conversion of a neutron into a proton, leading to a decrease in the mass number of the nucleus.
When did The Tail of Beta Lyrae happen?
The Tail of Beta Lyrae happened in 1983.
What is the temperature of Beta Phoenicis?
Its surface temperature is 4950 K.
How does a nucleus change when beta decay of the nucleus occurs?
The atomic number increases by one unit when a beta decay occurs.
What is the surfuce temperature on the Beta star?
Beta stars, such as Beta Centauri or Beta Scorpii, refer to specific stars in different constellations, each with varying surface temperatures. For example, Beta Centauri (also known as Hadar) has a surface temperature of approximately 25,000 K, making it a hot, blue giant. If you are referring to a specific Beta star, please provide its name for a more accurate temperature estimate.
