Direct current

Direct current
     Dc  (direct current) is the  unidirectional  flow or movement of electric charge carriers .The intensity of thebcurrent can vary with time but the general direction of movement stays the same all times. As an adjective the term DC is used in reference to voltage whose polarity never reverses.

What is electric current,

what is current?
  An Electric current is a flow of electric charge. This charge is aften carried by moving electron in a conductor.
    A current  1 amp= 1 coulombs (6.24X 10^18) electrons is moving past a single point in a circuit in 1seconds
     unit  =amps
                                       I = V/R

Electric grounding

What is grounding?
   A ground is the conductive connection between the earth or other conductive matireial in the place of earth and electric circuit or a piece of equipment.
     The principle reason of facilitating the grounding is to enable immediate diversion of heavy fault current in the event of a circuit fault  there by protection is provided against electric circuit shock hazards to people and animals.
