Current per unit cross-sectional area is known ascurrent density. It is expressed in amperes persquare meter, amperes per square centimeter, or amperes per square millimeter. Current density can also be expressed in amperes per circular mil. In general, the greater the current in a conductor, ...
To summarize,a semiconductor is a solid with a finite energy gap below 4 eV,which results in a moderate conductivity and carrier density at room temperature. By doping the semiconductor in a controlled fashion,the conductivity and carrier density can be varied over several orders of magnitude. Du...

An object may be very heavy (have a high mass) but have low density because it weighs very little per unit of volume. TL;DR (Too Long; Didn't Read) Density is the ratio of mass to volume. Low density objects have a low mass per unit volume because they contain fewer particles....
Densityis a measure of the mass of an object per unit volume. It is a measure of how compact the atoms inside of an object is.Densityis just a ratio of mass to volume. What determines the mass of an object? Everything is made up of matter, stars, mount everest, and you....
A conductor contains electrons that are generally in random motion but when some voltage is applied across the conductor then the electrons start flowing across in a direction towards the positive terminal of the battery and the current starts flowing in the conductor. Answer and Explanation: For...
They can trace trajectories that can cross any point in the area such that the number of possible trajectories is the number of points in the area, which is just the area itself. Which means that the current density JJ is just the flow jj divided by the areaextension of the finish-area...
(jpeg), discard some image data to achieve smaller file sizes but may introduce slight artifacts or quality degradation. what is the relationship between dots per inch (dpi) and raster images? dpi refers to the resolution or density of dots or pixels in a printed image. raster images are ...
Another way of describing a vector like it’s a scientific thing is this: A tuple that has scalars (numbers or values from a dataset). According toBritannica, examples of scalars include density, energy, volume, time, and mass. The thing to know about scalars is that they don’t possess...
