What is stability of transistor?
Transistors need thermal stabilization because the operating point of a transistor junction, similar to a diode, is affected by temperature. In fact, this can cause thermal runaway, and device destruction, if the circuit design does not compensate for this. Answer mostly correct but the operating point of a transistor must remain fixed as temperature varies whether going low or higher. that is mainly the concern about. not runaway that is caused by bad design.
Is stone a good or bad thermal insulator?
Stone is most definitely not a good thermal insulator. It changes its temperature quickly with the surrounding environment. In fact, stone is a thermal conductor and will pass heat or cold right to the adjacent materials.
Does copper possess high or low thermal conductivity?
Copper has a high thermal conductivity, not low. This is a good generalization of any metal, although they vary in conductivity.
What is the range of thermal efficiency of good IC engine at rated load?
60 to 70%
What is the efficiency of an engine that gives off 70 percent thermal energy?
It is not a good efficiency engine.
Is fabric a good thermal insulator?
Yes, fabric can be a good thermal insulator. Natural fibers such as wool, cotton, and silk are known for their insulating properties due to their ability to trap air. Additionally, specialized synthetic fabrics like fleece and thermal materials are designed to provide excellent thermal insulation.

What features of an object provide good stability?
It depends on the shape of the object and how its mass is distrubuted
What makes good thermal insulators and conductors?
Good thermal insulators have high thermal resistance and low thermal conductivity, which helps to slow down heat transfer. Materials like foam, fiberglass, and wool are good insulators. Good thermal conductors, on the other hand, have high thermal conductivity and allow heat to transfer quickly. Copper, aluminum, and silver are examples of good thermal conductors.
Is acrylic a good thermal insulator?
No, acrylic is not a good thermal insulator. It has low thermal resistance and can allow heat to transfer easily.
Is acrylic a good electrical and thermal insulater?
Acrylic is not a good electrical insulator because it is a conductor of electricity. However, it can be a good thermal insulator as it has low thermal conductivity.
Should the ceramic tiles on a shuttle be good thermal conductors?
No. They should be good thermal insulators.
Is krypton a good thermal conductor?
No, krypton is not a good thermal conductor. It is a noble gas and has very low thermal conductivity compared to other materials.
Are napkins insulators?
Napkins are not good insulators, as they are thin and do not provide much thermal or electrical resistance. They are more commonly used for wiping and cleaning purposes.
Can heat move easily through a good thermal conductor?
Yes, that is what "good thermal conductor" means.
Why are dividends good for investors?
Dividends are good for investors because they provide a steady stream of income, offer a way to share in a company's profits, and can indicate financial stability and growth potential.
Why studied btech and choosing bank jobs?
frankly speaking after b.tech i need good job ...which provide me stability and good money and i see bank as good option...so i prefer banking sector as my career....
