The electrons still rotate around the nucleus due to the attraction force between the protons in the nucleus and electrons. The electrons may leave the atom and move freely due to the weakness of...
The inductive reactance is different from the ohmic resistance where the inductive reactance for a coil of zero resistance does not cause loss in electric energy, because the current resistance is due to the...
AC dynamo generates an alternating current which its intensity increases from zero to maximum value then drops to zero again in the first half cycle, next to that, the current direction is reversed and...
Fleming’s left hand rule is used to determine the direction of the magnetic force acting on a straight wire carrying an electric current placed perpendicular to a magnetic field, Let the pointer & thumb...
