How does laser printer works? When a text or image is entered into the CPU, it makes a series of varying voltages. This controls a LED (light emitting diode) in the printer. Th
Weber; Wb (after W. Weber, 1804-1891): The derived SI unit of magnetic flux equivalent to the flux that, relating a circuit of one turn, generates in it an electromotive force
The Venturimeter (see figure) is a device used to calculate the flow speed of a fluid in a pipe. At the throat, the area is decreased from A to a and the velocity is increased from
Although it needs not concern us further, we also consider that the flow is irrotational. To check for this property, let a tiny grain of dust goes with the fluid. Although this te
