Electricity

A form of energy comes from a flow of electric charges (Electrons)
                                 along a path.

                     Electric Current

The flow of electric charges Electrons along a closed path.

The Electric Circuit: The closed path for transmitting an electric current.

               To obtain an electric current,
               the electric circuit must be
                closed. “Without breaks”
   1- A source of electricity: Battery / Wall socket “transfers the
      electric current from the power lines to the building

2- An electric device (Lamp): An indicator.

3- Metal wire: connects all components and transfers
   (conducts) the electricity from the battery to the lamp.

4- Switch (Key): controls opening and closing the circuit and it

       may be manual as the wall switch for light and may be

             automatic as internal switch on a thermostat
               “adjust the temperature in the refrigerator”
