## Difference between bipolar junction transistor (BJT) & field effect transistor (FET)

BJT and FET are electronic devices.The basic difference between BJT and FET is that bipolar junction transistor is the bipolar and current control device,while FET (field effect transistor) is the uni junction transistor.It is a voltage control device. The Difference between bjt and fet                            BJT     ...

## Difference between mechanical and matter waves with examples

Mechanical waves and matter waves are the types of waves.The basic difference between mechanical waves and matter waves is that mechanical waves required medium for propagation such as sound waves,while matter waves are the waves which contain information about the particles,these waves also known as de broglie waves. Mechanical waves The waves which required any medium for their propagation are ...

## Difference between conservative and conservative force with examples

Conservative and non conservative force examples are given in which Gravitational forces,Magnetic force,Electrostatic force,Elastic spring force,Electric force are conservative force examples while frictional force,air resistance force,force of gravity are non conservative force examples. What are conservative forces? Those  forces which allows the opportunity of two way conversion among potential and kinetic energies are said to be conservative forces. Conservative force ...

## Difference between dot product and cross product in tabular form

Vector dot product and cross product are two types of vector product,the basic difference between dot product and scalar product is that in dot product,product of two vectors is equal to scalar quantity while in scalar product,product of two vectors is equal to vector quantity.  dot product Vs cross product   Dot product or scalar product  Cross product or vector ...

## Difference between reversible and irreversible process in thermodynamics

The basic difference between reversible and irreversible process is that in reversible process the system remains in thermodynamic equilibrium ,while in irreversible process the system does not remain in thermodynamic equilibrium. Reversible process in thermodynamics “A process which can be retracted in exactly reverse order without producing any change in the surroundings is called reversible process”. In the reverse process, ...

## Derivation of First equation of motion in physics

First equation of motion (Vf =Vi + at)  deals with final velocity,initial velocity,acceleration and time.We can use 1st equation of motion to find final velocity,initial velocity,acceleration and time. First equation of motion derivation Consider a body is moving with initial velocity “Vi” with uniform acceleration “a” as shown in figure.After time “t” its velocity becomes “Vf”.The total distance covered by ...

## Capacitance of a capacitor

Capacitance of a capacitor is the ability of capacitor  to store an electric  charge per unit of voltage across its plates of a capacitor .Capacitance is find by dividing electric charge with voltage by the formula C=Q/V .Its unit is Farad. Formula Its formula is given as: C=Q/V Where C is capacitance,Q is voltage,and V is voltage.We can also find charge Q ...

## kepler’s laws of planetary motion definition and equation

Kepler’s laws of planetary motion are expressed as:(1) All the planets move around the Sun in the  elliptical orbits, having the Sun as one of the foci. (2) A radius vector joining any planet to  Sun sweeps out equal areas in equal intervals of time.(3) The square of the period of any planet about the sun is proportional to the cube of the ...
