Arcing Ground

Definition: Arcing ground is the surge, which is produced if the neutral is not connected to the earth. The phenomenon of arcing ground occurs in the ungrounded three-phase systems because of the flow of the capacitance current.The capacitive current is the current flow between the conductors when the voltage is applied to it. The voltage across…

Types of Fuses

The fuse is the current interrupting devices which break or open the circuit by fusing the element and thus remove the faulty device from the main supply circuit. The fuses are mainly classified into two types, depends on the input supply voltages they are the AC fuses and the DC fuses. The different types of…

Types of Circuit Breaker

There are several methods of classification of circuit breakers. The most general way of the rating of a circuit breaker is by the arc extinction medium. The arc extinction can easily be done by using the different medium like air, insulator, gas, vacuum, dielectric, etc. By the arc extinction medium, the circuit breaker is categorised into…

Difference Between Cell and Battery

The cell and battery both store the chemical energy and then transforms the stored chemical energy into an electrical energy. One of the major difference between the cell and the battery is that the cell is the single unit, whereas the battery is the group of cells. Some other differences between them are explained below…

Zero Sequence Current

Definition: The unbalanced current flows in the circuit during the earth fault is known as the zero sequence current or the DC component of the fault current.The zero phase sequence means the magnitude of three phases has zero phase displacement.The three vector lines represent the zero sequence current and it is detected by adding the…

Power Factor Correction

Definition: The power factor correction means bringing the power factor of an AC circuit nearer to one by using the equipment which absorbs or supply the reactive power to the circuit. Usually, the power factor correction can be done by using the capacitor and the synchronous motor in the circuit.The power factor correction will not…

Difference Between Resistance & Resistivity

One of the major difference between the resistance and the resistivity of the material is that the resistance opposes the flow of free electrons whereas the resistivity is the property of the material which defines the resistance of the material having specific dimension. The other differences between them are explained below in the comparison chart.…

Difference Between Dielectric & Insulator

The dielectric and insulator are differentiated from their applications. One of the major difference between the dielectric and insulator is that the dielectric stores the electrical charges while the insulator opposes the flow of electrons. Some other differences between them are explained below in the comparison chart. Content: Dielectric V/S Insulator Comparison Chart Definition Key Differences…

Electric Motor

Definition: Electric motor is the electro-mechanical machine which converts the electrical energy into mechanical energy. In other words, the devices which produce rotational force is known as the motor. The working principle of the electric motor mainly depends on the interaction of magnetic and electric field.The electric motor is mainly classified into two types. They…

Difference Between EMF and Voltage

One of the major difference between the EMF and voltage is that EMF is the energy supplied to the charge, whereas the voltage is the energy requires to move the unit charge from one point to another. The other differences between them are explained below in the comparison chart. Content: EMF V/S Voltage Comparison Chart…
