Electricity and direct current circuits
:explode:
ELECTRICAL ENERGY
atoms
protons
(Positive charge)
neutrons
( Neutral charge)
electrons
( Negative charge)
Electricity
Electricity current
Electrical energy
OPEN AND CLOSED CIRCUITES
OPEN
OFF: The lamp isn´t lit
CLOSED
ON: the lamp is lit
SHORT CIRCUIT
Occurs when the electric current is transported by wires without passing a load device
CONDUCTORS & INSULATORS
insulators
wood
plastic
definition
A material that doesn´t letelectric current flow through it
cardboard
conductors
copper
aluminium
silver
definition
a material that lets electric current flow through it
Gold
MAIN ELECTRIC VARIABLES
VOLTAGE
This is the different in the change between two points, which makes the electrons move.(V)
RESISTANCE
This si the opposition to the flow of the electric current.(OHM(Came up an equaltion relating these three variables I=V/R))
CURRENT:
This is the intensity of the current or the amount of electrons flowing through a conductor over a certain time.(A)
TYPES OF CIRCUITES
SERIES CIRCUITES
All the components are connected one after another
PARALLEL CIRCUITES
The load devices are connected on different of the wire
SERIES-PARALLELCOMBINATION CIRCUITES
These circuites devices connected in series and in parallel
ELECTRIC CIRCUITS. COMPONENTS
a electrical circuit is a series of interconnected components that an electric current flows through to produce an effect.
components
there are many components in an electric circuit
Power sources
conductors
load devices
control devices
CONVERTING ELECTRICAL ENERGY
LIGHT: We can convert electricity trough load devices
HEAT: When electrons move through a conductor or load devices, they create friction with the material as they through
MOTION: We can also convert electricity to motion using a motor
SOUND: We can use electrical energy to transmit sounds through microphones and we can produce sound effects
REPRESENTING CIRCUITS:electrical schematics
electrical schematic
We represent electrical circuits with a very simple drawing called electrical schematic
standardised symbol
Every component in a circuit has an standardised symbol to represnt it in a simple way that anybody can understand.
