Graphite is a good conductor of electricity, as its atoms bond to form sheets of tightly packed molecules, with gaps between. Delocalised electrons are free to move in these gaps, and as current is applied, so the electrons move, repelling one another in a domino effect, thoughout the structure. This may be right, hope so as its a question I was asked on my course recently!
What else can I help you with?
How do you select a conductor size?
Select a conductor size based on the current carrying capacity needed for the electrical load, taking into account factors such as voltage drop, ambient temperature, and type of installation. Refer to applicable electrical codes and standards to ensure the conductor size meets safety requirements for the specific application. Consult with an electrical engineer or use online calculators to determine the appropriate conductor size.
How can one determine the drift velocity of charged particles in a conductor?
To determine the drift velocity of charged particles in a conductor, one can use the formula: drift velocity current / (number density of charge carriers cross-sectional area charge of each carrier). This formula takes into account the current flowing through the conductor, the density of charge carriers, the cross-sectional area of the conductor, and the charge of each carrier. By plugging in these values, one can calculate the drift velocity of the charged particles.
What is the Kubo formula and how is it used to calculate the electrical conductivity of materials?
The Kubo formula is a mathematical equation used to calculate the electrical conductivity of materials. It takes into account the interactions between electrons and the crystal lattice structure of the material. By using the Kubo formula, scientists and engineers can predict how well a material will conduct electricity based on its physical properties.
What is compression in a structure?
Compression in a structure occurs when external loads cause the structure to shorten or compact. This type of stress typically tends to compress, rather than stretch, the material. It is important for engineers to account for compression forces when designing structures to ensure they can safely support the expected loads.
What energy sources generates the most amount of the worlds electricity?
The world's electricity is mainly generated by fossil fuels like coal, natural gas, and oil, which collectively account for the largest share. However, renewable energy sources such as hydropower, wind, and solar are rapidly growing and are becoming significant contributors to global electricity generation as well.
How does the structure of graphite account for the design of graphite electrodes?
The layered structure of graphite, in which carbon atoms are arranged in sheets, allows for easy electron mobility, making graphite a good conductor of electricity. This property is essential for graphite electrodes to efficiently carry and transfer electrical current during processes like electrolysis or electrochemical reactions. Additionally, the high thermal stability and resistance to chemical reactions of graphite make it suitable for use in harsh environments.
Is electricity a liability or asset?
Electricity expense is an expense account while accrued electricity payable is a liability account
Diamond and graphite are both forms of carbon.Diamond is hard Graphite is soft and flaky How could these different properties be explained?
Diamond and graphite have different structures which account for their different properties. Graphite is arranged into sheets which are easily removed. Diamond, on the other hand, is a network solid that has very strong bonds and intermolecular forces holding it together.
Is graphite dense?
For experimental calculation: Mass the graphite sample with a scale (make sure to take into account the mass of whatever is holding the graphite sample - either zero the scale with the beaker/holder before adding the sample or subtract the mass of the beaker/holder from the total mass). Measure volume by measuring water displacement when graphite sample is added to a measured amount of water. Density = (Mass) / (Volume)
Is an electricity account an example of a trade account payable?
No Electricity account is non-trade accounts payable as trade accounts payable are those suppliers only from which company purchase supplies for sale purpose.
How do you account for fair and poor conductors of electricity?
Fair conductors of electricity have some electrons that can move freely, allowing for the flow of electricity. Poor conductors have fewer free electrons, hindering the flow of electricity. This difference is due to the material's atomic structure and its ability to facilitate the movement of charged particles.
What is the structure of protein that can account for buffering?
the ionized species or the zwitterion
Where can you purchase cheap business electricity?
One can find the cheap electricity for businesses by getting a quote from companies such as uSwitch. uSwitch compares the prices from all electricity suppliers available in the area, taking into account the amount of electricity used.
What are the properties of lead?
Lead has a blue-gray color. It is the softest and heaviest of the common metals. It is very malleable and ductile, but has no elastic strength, and its tensile strength is so low that it cannot be drawn readily into fine wires. It is a poor conductor of heat and electricity. On account of its softness it can be readily squeezed through a press and thus shaped into rods or pipes. It melts at about 600° F.
How does the basic structure of DNA account for both the unity?
phosphates and amino acids
How many atoms are there in a graphite pencil dot?
There are 6.02 x 10^23 molecules per mole of any substance: this is 0.6 trillion trillion molecules.A mole of water is only 18 grams. A regular wood pencil weighs about half of that. There will be fewer molecules of wood but more atoms per molecule. But you are still talking a range of hundreds of billions of trillions of atoms (10^22) in an item the size of a pencil.
How do you select a conductor size?
