What is the difference between direct and indirect energy?
The band gap represents the minimum energy difference between the top of the valence band and the bottom of the conduction band, However, the top of the valence band and the bottom of the conduction band are not generally at the same value of the electron momentum. In a direct band gap semiconductor, the top of the valence band and the bottom of the conduction band occur at the same value of momentum.In an indirect band gap semiconductor, the maximum energy of the valence band occurs at a different value of momentum to the minimum in the conduction band energy
When only three colour are stripes present on the body of a resistance what is the replaced value of its tolerance?
If there is no fourth band (the tolerance band) then the component's tolerance value is 20%.
Who is the group for the cryptic clue not death in the orient?
The group referred to in the cryptic clue "not death in the orient" is likely the band "The Rolling Stones." This is because "not death" sounds like "rolling," and the term "in the orient" could allude to stones or rocks.
What is the value of band gap of zinc selenide?
The band gap of zinc selenide is approximately 2.7 electron volts (eV). This value indicates the energy difference between the valence band and the conduction band in the material. Zinc selenide is a semiconductor commonly used in optoelectronic applications due to its wide band gap.
What is the value in ohms of a resistor colored brown red yellow gold?
The first band, brown, indicates the digit 1.The second band, red, indicates the digit 2.The third band indicates the multiplier. For yellow, this is 10000.12x10000 = 120,000 ohms.The last band is an indication of the tolerance of the resistor; gold means the actual value is within 5% of the stated value.
Energy Band gap value for calcium carbonate and barium carbonate?
The energy band gap value for calcium carbonate (CaCO3) is around 5.6 eV, while for barium carbonate (BaCO3) it is approximately 6.3 eV. These values indicate the amount of energy required to promote an electron from the valence band to the conduction band in the respective materials.
What is the value of 10k gold band?
10k is the equivelent to our 9ct Gold in England I believe. The value depends on what you can sell it for, it all depends on weight and what you have mounted on the band, Diamonds, Emeralds, Rubies etc all help to increase the value
How does the Council Tax system work?
England's Council Tax System is based on the value of a house at a particular fixed time. It is controlled by a government organization called "VOA." The value of the property does not change until a set time of reavaluation is established by the VOA. Then the value of the each dwelling is assessed according to the values in each Band. Each Band is part of a value chart; Bands A - H. They use this chart to categorize the values from which to base the tax value upon. Band A, being the least expensive and Band H, the higher priced properties.
What is the value of a Winchester Model 190 with a barrel band?
Answer to the value of a Winchester 190about $150 used, and $200-$250 new.
What is the value of a Marine Band harmonica No 1873 by M Hohner?
Its around £26
How can you find a resistance of resistor without DMM explain the method with the help of example?
Hi You can find the value of the resistor by using colour code printed on the resistor. 1. Hold the resistor such that the colour code starts from left. 2. Each of the colour bands present on the resistor specifies a value. 3. The first colour band represents the first significant figure, the second band represents the second significant figure and the third band indicates the multiplier. The fourth band represents the tolerance. Gold band- 5%, Silver band-10%, No band-20% 4.Find the appropriate values for the colour by using the chart 1. 5. Find the value of the resistor by using the formula 1. Chart1 Example: Here first band represent brown. Second band represent black. Third band represent red . Fourth band represent gold. The value of resistor = 10 x 102 ± 5% = 1kΩ ± 5%
