One of the significant difference between the AC and DC bridge is that the AC bridge is used for measuring the unknown impedance of the circuit whereas the DC bridge is used for measuring the unknown resistance of the circuit. The other differences between the AC and DC bridge are shown below in the comparison …
Definition: The instrument whose working depends on the principle of attraction or repulsion of electrodes that carry electrical charges such type of instrument is known as the electrostatic instrument. In other words, the instrument which uses the static electric field for producing the deflecting torque is known as the electrostatic instrument. The electrostatic instrument is …
Definition: The synchroscope is a device which shows the correct instant at which the two systems are synchronised. The terms ‘synchronize’ means the machines of equal frequency and voltage are operating parallel to each other. The synchroscope consists the two-phase wound stator and rotor. The alternators provide the two-phase supply to the synchroscope. If any …
Definition: The temperature transducer converts the thermal energy into a physical quantity likes the displacement, pressure and electrical signal etc. It is an electrical device used for automatic measuring of temperature. The main principle of the temperature transducer is to measure the heat and transfer the information after converting it into the readable form. The …
One of the significant difference between the moving iron and moving coil instrument is that in moving iron instrument, the soft iron system is used for measuring mechanism. Whereas in moving coil instrument the conductor coil is used for DC measurement. The other differences between the moving iron and moving coil instrument are shown below …

Definition: The frequency is the number of oscillation per unit time. It is used for defining the cyclic process like rotation, oscillation, wave etc. The completion of the cyclic process at particular interval of time is known as the frequency. The SI unit of the frequency is Hertz. The symbol λ represents it. The one …
The major difference between the AC and DC voltage is that in AC voltage the polarity of the wave changes with the time whereas the polarity of the DC voltage always remains same. The other differences between the AC and DC voltage are shown below in the comparison chart. Content: AC Voltage Vs DC Voltage Comparison …
The meter is generally used for measuring the particular quantity. The unit of current is ampere, and the meter which measures the current is known as the ammeter. The rectifier ammeter uses the moving coil along with the rectifier for measuring the current. The main use of the rectifier is to convert the alternating current into …
The most crucial difference between the AC and the DC transmission line is that the AC transmission line uses three conductors for power transmission whereas the DC transmission line requires two conductors. The other differences between the AC and DC transmission lines are explained below in the comparison chart. The transmission line is a closed …
The measurement is the result of the comparison of standard and the unknown quantity. The result of the measured quantity is generally expressed in numeric forms. In other words, the measurement is the process through which the physical parameters like heat, displacement, force etc. is converted into the easily readable numeric value. Methods of Measurement …
