BASIC ELECTRICITY
-
-
MATERIALS THAT LET ELECTRIC CURRENT FLOW THROUGH THEM (FOR EXAMPLE, COPPER) ARE CALLED CONDUCTORS. MATERIALS THAT DO NOTLET ELECTRIC CURRENT FLOW TRHOUGH THEM (PLASTIC) ARE CALLED INSULATORS

-
CONDUCTORS
COMPONENTS THAT TRANSPORT THE ELECTRICAL ENERGY FROM THE POWER SOURCES TO THE LOAD DEVICES; IN OTHER WORDS, THE ELECTRIC CURRENT FLOWS TROUGH THESE COMPONENTS.
POWER SOURCES
COMPONENTS THAT SUPPLY THE NECESSARY ELECTRICAL ENERGY TO THE REST OF THE CIRCUIT IN OIRDER TO MOVE THE ELECRONS.
COMPONENTS OF A CIRCUIT
COMPONETS
CELL: SUPPLIES ELECTRICAL ENERGY TO THE REST OF THE CIRCUIT.
CELL HAVE A POSITIVE TERMINAL AND A NEGATIVE TERMINAL; THIS LETS THEM SUPPLY ELECTRC CURRENT TO THE CIRCUIT WHEN THEY ARE CONNECTED.
-
-
-
-
TYPES OF CIRCUITS
Series circuits: all the components are connected one after the other. 
-
SERIE-PARALLEL COMBINATION CIRCUITS: THESE CICUITS CONTAINS DEVICES CONNECTED IN SERIES AND IN PARALLEL
WHEN WE ANALYSE ELECTRICAL CIRCUITS, WE NEED TO DEFINE A SERIES OF VARIABLES. TO UNDERSTAND THIS, LETS IMAGINE A CIRCUIT LIKE THE ONE IN THE FIGURE, WITH A CELL AND A LAMP.
-
CURRENT. THIS ISS THE INTENSITY OF THE CURRENT ON THE AMONT OF ELECTRONS TROUGH A CONDUCTOR OVER A CERTAIN TIME
VOLTAGE. THIS IS THE DIFFERENCE IN THE CHARGE BETWEEN TWO POINTS AND NEGATIVE , WICH MAKES, THE ELECTRONS MOVE
RESISTANCE. THIS IS THE OPPOSITION TO THE FLOW OF THE ELECTRIC CURRENT. ITS UNIT OF MEASSUREMENT IN THE INTERNATIONAL SYSTEM IS THE ORM.
-
-
THIS ECUATION IS NOW AS OHM LAW WICH STATES. THE CURRENT IN A CIRCUIT IS DIRECTLY PROPORTIONALY TO THE ELECTRIC POTENTIAL DIFEERENT IMPRESED ACROSS IT ENDS AT IN VERSELY PROPOTIONAL TO THE TOTAL RESISTANCE OFFERED BY THE EXTERNAL CIRCUIT
