Davisson-Germer experiment (C.J. Davisson, L.H. Germer; 1927)
An experiment which conclusively confirmed the wave nature of electrons; diffraction patterns were observed through an electron beam penetrating in a nickel target.
Q. What is direction of the current? The path of the magnetic field at the centre of a horizontal current-carrying loop of wire is straight downward. The magnetic field is affe
Definition: The electric field in a region is shown by continues lines (also known as lines of force). Field line is an imaginary line along which a positive test charge will move
Resistance: Resistance is the opposition to the motion of electrons. This arises as a result of collision of moving electrons. The unit of resistance is "ohm" represented by
