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 ...

Read More »## 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 ...

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 ...

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, ...

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 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 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 ...
