  • Transistor

    In order to explain the working of the transistor, let us take an example of an NPN transistor. The same principles are used for PNP transistor except that the current carriers are holes and the voltages are reversed. Operation of NPN Transistor. The emitter of NPN device is made by n-type material, hence the majority carriers are electrons.

  • Bernoulli's Principle: Definition, Equation, Examples

    Dec 28, 2021The most common example of Bernoulli's principle is that of a fluid flowing through a horizontal pipe, which narrows in the middle and then opens up again. This is easy to work out with Bernoulli's principle, but you also need to make use of the continuity equation to work it out, which states: ρ A 1 v 1 = ρ A 2 v 2. ρA_1v_1= ρA_2v_2 ρA1.

  • Butterfly Valve

    Butterfly valves are among the family of quarter-turn valves and work very similar to ball valves. The "butterfly" is a disk connected to a rod. It closes when the rod rotates the disc by a quarter turn to a position perpendicular to the flow direction (right image in Figure 1). When the valve opens, the disk is rotated back to allow the
