Electric Circuit

 

The Simple Electric Circuit

 

When a dry cell or battery (source), bulb (load), and wires (connections or path) are connected the bulb lights.

When wires are disconnected the bulb will not light.

Four basic parts of a Simple Electric Circuit:

     1.  Source - Dry cell

     2.  Load - Bulb

     3.  Connections - Wires

     4. Means of Control - Switch

Parts of an Electric Circuit:

1.Source – where the electric current or electricity come from. Examples: generator or battery (dry and wet cell)

2.Load – these are devices that consume electricity also called resistance. Examples: light bulb, electric fan, refrigerator, electric iron, etc.

3.Path or Connection – is the pathway in a circuit where electricity flows or pass through. It is made up of conducting materials called conductors. Example: copper wire

4.    Means of Control – also called circuit breakers or the switch that control the flows of electricity. If the switch is “on” the electric current or electricity can flow in a circuit and if it is “off” the electricity cannot flow.

      An Electric circuit is made up of source, load, and  connections or path  which electric current flows if they are connected.

     A circuit could be closed or open:

     

When the Switch is “ON” the circuit is closed and the electrons flow.

When the Switch is “OFF” the circuit is open and the electrons cannot flow.
