The basic working principle of a DC motor is: "whenever a current carrying conductor is placed in a magnetic field, it ...
Working principle of Pitot tube When a solid body is kept centrally, and stationery in a pipeline with flowing fluid, the velocity of the fluid starts reducing (at the same time the pressure fluid increases due to the conversion of kinetic energy into pressure energy) due to the presence of the body.
Sep 07, 2019· Construction. The construction of it is similar to that of N-P-N transistor but here the differences arise in the polarities of the voltages applied. The characteristics tend to differ because here the voltage has been applied in between the terminal base is negative and that of the emitter is positive.
The construction of LED is similar to the normal p-n junction diode except that gallium, phosphorus and arsenic materials are used for construction instead of silicon or germanium materials. In normal p-n junction diodes, silicon is most widely used because it is less sensitive to the temperature. ... Light emitting diode (LED) symbol.
Jun 12, 2020· The working principle and construction of an Optical Pyrometer are quite simple. We have drawn an experimental model of this type of temperature sensors.It is a measuring instrument that measures temperature of a hot glowing object.. The instrument has an illuminated reference, with which the brightness of that of the hot body is matched by controlling the input electric current of the reference.

What is Unijunction Transistor (UJT) UJT stands for UniJunction Transistor.It is a three terminal semiconductor switching device. The Unijunction Transistor is a simple device that consists of a bar of n-type silicon material with a non-rectifying contact at either end (base 1 and base 2), and with a rectifying contact (emitter) alloyed into the bar part way along its length, to form the only ...
Apr 01, 2020· Working Principle of Solar Cell. When light reaches the p-n junction, the light photons can easily enter in the junction, through very thin p-type layer.The light energy, in the form of photons, supplies sufficient energy to the junction to create a number of electron-hole pairs.
What is Contactor : Construction, Types and Applications. ... Working Principle of Contactors. An electromagnetic field is generated whenever current flows where the moving coils attract each other. A large amount of current is drawn initially by an electromagnetic coil. The moving contact is pushed forward by moving core, as a result, the ...
The working principle of the colorimeter is based on Beer-Lambert's law which states that the amount of light absorbed by a color solution is directly proportional to the concentration of the solution and the length of a light path through the solution. A ∝ cl. Where, A = Absorbance / Optical density of solution
Working. When the rotor is stationary, there is no relative motion between a magnetic field and winding, the output voltage is zero. As the rotor speed increases, the relative motion between a magnetic field and winding also increases and hence the output voltage induced in the winding.
Sep 28, 2019· The armature core consists of armature windings, slip rings, and brushes.The armature develops armature current when the coil cuts the magnetic flux such that an armature flux is also developed. The slips rings are responsible for the smoother operation between the brushes in order to avoid twisting of the winding.
