## Difference Between Electromotive Force & Potential Difference

The potential difference and electromotive force (emf) both is the form of energy. One of the major difference between the emf and potential difference is that the emf is caused by converting the other form of energy into electrical energy whereas in potential difference the electrical energy is converted into other forms of energy. Some …

## Difference between Electric & Magnetic Field

The one of the major difference between the magnetic and electric field is that the electric field induces around the static charge particle which is either negative or positive, whereas the magnetic field produces around the poles (i.e., the north and south pole) of the magnet. Some other differences between them are explained below in …

## Difference Between Power and Torque

The one of the major difference between power and torque is that the power is the amount of work done by an object whereas the torque is the tendency of the force to rotate the object in a particular direction. Some other differences between them are explained below in the comparison chart Content: Power Vs …

## Difference Between Voltage & Current

The voltage and current are the two major aspects of electricity.The voltage is the type of the electromagnetic force whose effect causes the flow of electrical current in the circuit. The magnitude of a voltage and current depends on each other, but these two terms are different from each other in some ways. One of …

## Difference Between Current Transformer (CT) & Potential Transformer (PT)

The electrical instruments are not directly connected to the meters or control apparatus of high voltage for safety purpose. The instrument transformers like voltage transformer and current transformer are used for connecting the electrical instruments to the measuring instruments.These transformers reduce the voltage and current from high value to the low value which can be …

## Difference Between Alternating Current (AC) & Direct Current (DC)

The conducting materials have free electrons which move from one atom to another when the potential difference is applied across them. This flow of electrons in a closed circuit is called current. On the basis of the direction of movement of electrons in a closed circuit, the electric current is mainly classified into two types, …

## Difference between Step-up and Step-down transformer

A transformer is a static device which transfers a.c electrical power from one circuit to the other at the same frequency, but the voltage level is usually changed. For economical reasons, electric power is required to be transmitted at high voltage whereas it has to be utilized at low voltage from a safety point of …

## Difference Between Resistance and Impedance

The Difference Between Resistance and Impedance is explained below keeping in mind the various factors like the basic definition of resistance and impedance, a type of circuit they work in, elements on which they depends, their symbolic representation, real and imaginary numbers, the effect of frequency on them, phase angle, power dissipation and energy stored. …

## Difference Between Synchronous and Asynchronous Motor

The Difference Between Synchronous and Asynchronous Motor are explained considering factors like its type, slip, requirement of additional power source, requirement of slip ring and brushes, their cost, efficiency, power factor, current supply, speed, self starting, effect in torque because of change in voltage, their operational speed and various applications of both Synchronous and Asynchronous …

## Difference Between Capacitor and Battery

The Difference Between Capacitor and Battery is explained considering factors like function of capacitor and battery, type of component they are, their usage, voltage, charging and discharging time, life cycle, cell voltage, cost, service life, charging temperature, specific power, potential difference, polarity, types and size. Difference Between Capacitor and Battery is shown below in the …
