Advantages: It has wide frequency response and large bandwidth. It is most convenient and least expensive amplifier. It provides high audio fidelity. It has low amplitude distortion. It provides low frequency distortion. Disadvantages: It has a tendency
The AC tachogenerator is used to measure the speed only in one direction. In AC tachogenerator the armature is provided with an AC winding, either single phase or three phase windings. Working: When the rotor is stationary
The well type monometer is widely used because of having only one leg. The main difference between a U-tube manometer and a well type manometer is that the U-tube is substituted by a large well such that
LED PN junction diode The LED emits light. The PN junction diode cannot emit light. The LED uses GaAs, GaAsP or GaP material. The PN junction diode silicon or germanium material. In LED all energy converted into
There are some advantages of DC tachogenerator which are given below. The DC tachogenerator has linear charactristic. In DC tachogenerator, temperature compensation is easily achived. It does not have zero speed error. It is capable to generate
There are some advantages of point contact diode which are given below. The point contact diode has very low forward resistance. The point contact diode has very low reverse resistance. It has very low junction capacitance. It
There are some advantages of induction generator which are given below. The induction generator is smaller in size per kilowatt output power. It needs less auxiliary equipment. Parallel operation is possible without hunting. The induction generator has
The other name of induction motor is a synchronous motor. It is most popularly used motors in many applications. An induction motor is an AC electric motor in which the electric current in the rotor used to
There are some important applications of Zener diode which are given below, The zener diode is used in voltage regulator circuits to provide regulated DC voltage. The zener diode is used for meter protection against damage from
There is difference between RTD and thermistor which are given below. RTD (Resistance Temperature Detector) Thermistor Here conductor us used which gives increase in resistance with increase in temperature.(i.e. PTC ) Here semiconductor is used which gives
