One of the major difference between the permittivity and the permeability is that the permittivity measures the obstruction generates by the material in the formation of an electric field. Whereas, the permeability measures the ability of the material to allow the magnetic lines of force to pass through it. The other differences between the permittivity …
Definition: The bridge which measures the inductance in terms of capacitance is known as Owen’s bridge. It works on the principle of comparison i.e., the value of the unknown inductor is compared with the standard capacitor. The connection diagram of Owen’s bridge is shown in the figure. The ab, bc, cd and da are the four arms …
Definition: The bridge uses for measuring the value of unknown resistance, inductance and capacitance, is known as the AC Bridge. The AC bridges are very convenient and give the accurate result of the measurement. The construction of the bridges is very simple. The bridge has four arms, one AC supply source and the balance detector. It …
Definition: The Anderson’s bridge gives the accurate measurement of self-inductance of the circuit. The bridge is the advanced form of Maxwell’s inductance capacitance bridge. In Anderson bridge, the unknown inductance is compared with the standard fixed capacitance which is connected between the two arms of the bridge. Constructions of Anderson’s Bridge The bridge has fours arms …
Definition: The Hay’s bridge is used for determining the self-inductance of the circuit. The bridge is the advanced form of Maxwell’s bridge. The Maxwell’s bridge is only appropriate for measuring the medium quality factor. Hence, for measuring the high-quality factor the Hays bridge is used in the circuit. In Hay’s bridge, the capacitor is connected …
Definition: The bridge used for the measurement of self-inductance of the circuit is known as the Maxwell bridge. It is the advanced form of the Wheatstone bridge. The Maxwell bridge works on the principle of the comparison, i.e., the value of unknown inductance is determined by comparing it with the known value or standard value. …
Definition: The device uses for the measurement of minimum resistance with the help of comparison method is known as the Wheatstone bridge. The value of unknown resistance is determined by comparing it with the known resistance. The Wheatstone bridge works on the principle of null deflection, i.e. the ratio of their resistances are equal, and no current …
The most significant difference between the charge and the current is that the charge is the physical property of matter, whereas the current is the rate of flow of charges. Some other differences between charge and current are explained below in the tabular form. The electric charge is the physical property of matter which experiences the …
Definition: The meter which is used for measuring the power of three phase supply is known as the three phase energy meter. The three phase meter is constructed by connecting the two single phase meter through the shaft. The total energy is the sum of the reading of both the elements. Working Principle of Three …
Definition: Creeping in energy meter is the phenomenon in which the aluminium disc rotates continuously when only the voltage is supplied to the pressure coil, and no current flows through the current coil. In other words, the creeping is the kind of error in which the energy meter consumes a very small amount of energy even …
