    The induced emf is sometimes called 'back emf' because a large current in a coil that is suddenly removed will cause the magnetic field in the coil to collapse and cause a current in the opposite direction.

    In a uniform electric field, the force on a charged particle is always in the same direction, leading to parabolic trajectories. In a uniform magnetic field, the force of charged particles is always right angles to the motion, resulting the circular paths (or) helical trajectories.

    K@Łp@N@ $Øđh!?? 6 years, 2 months ago

    MOBILITY OF THE ELECTRON AND CURRENT Mobility of electron (ue) is defined as the drift velocity of electron per unit electric field applied. ue= drift velocity/electric field= Vd/E Thus                                 Vd=ueE The  SI unit of mobility is m2s-1V-1 or ms-1N-1C As  by the relation of the current and drift velocity (already discussed) I=Anevd (1) By putting value of vd in above equation we get I=AneueE OHM’S LAW Statement:– Ohm’s law states that the current (I) flowing through a conductor is directly proportional to the potential difference (V) across the ends of the conductor,provided physical conditions of the conductors such as temperature,mechanical strain etc. Are kept constant i.e. IαV Or                                                   VαI or V= RI Or                                                   V/I=R=a constant Where R is known as resistance of the conductor . It depends upon the length ,shape and the nature of the material of the conductor. The variation between potential difference (V) and current (I) through a conductor is a straight line. Deduction of Ohm’s Law: As drift velocity is given by Vd=eEt/m But                         Electric field across the conductor of length l is E=V/l Thus                              Vd=e V/ml Also,                              I=Anevd By putting value of vd in the equation of I (equation 1 of relation of the current and drift velocity),we get I=Ane(eV/ml)=(Ane2/ml)V Or                        V/I=ml/Ane2=R Where R is a constant for a given conductor. It is known as the resistance of the conductor. Thus                                  V=RI This  is Ohm’s law.

    Nisha Gupta 6 years, 2 months ago

    If u will avoid using mobile phone and give that time in your studies then u will have enough time for studies also take healthy diet so u can concentrate on that topic you should make your mind to study regular make short time table for yourself every day and give tasks to complete topics on that day and if not completed you should punish yourself as if you have not completed the task then as a punishment you will study one hour extra or will not watch your favourite serial or will not go to play in this way you can do regular studies

    An N-Type semiconductor is created by adding pentavalent impurities like phosphorus (P), arsenic (As), antimony (Sb), or bismuth (Bi).
    P-Type Semiconductor. The addition of trivalent impurities such as boron, aluminum or gallium to an intrinsic semiconductor creates deficiencies of valence electrons, called "holes". It is typical to use B2H6 diborane gas to diffuse boron into the silicon material.
