in an electric circuit, short circuit occurs when the electric current is transported by the wires whitout passing things thrugh a load device.
types of circuit:
circuits can have diferent characteristics depending on how we arrange the load devices
series circuit: in these circuits , all the componenets are connected one after the other .this way , all the current flows through all the load devices .there is only one possible path for the electric current to flow through
the same current flow through all load devices
if one is off all is off
parallel circuits:in these circuits , the load devices are connected on different branches of the wire .
the current does not flow equally through all the load devices .if one is broken the rest continiu working
series parallel conbination circuits :these circuits contain devices connected in series and in parallel . in this case ,the circuits have properties of both series circuits and parallel circuits
open circuits:a circuit is open when the energy of the power source cannot reach the load devices so the electric curren cant flow
a circuit is closed when the energy of the power source reaches the load devices so the electric current flow

load devices

-
Resistor a load device that opposes the flow of the electrical current.converts electrical enegy to heat energy.
-
electric circuits is a series of interconnected components that an electric current flow through to produce an effect (like light,heat,sound or motion)
load deveces:components that receive the electrical energy fronm the power sources and comvert it to other types of usefull energy
control devices: devices that regulate the circuit ; in other words they allow or prevent the flow of electric current through the circuit.
power sources:components that supply nessesary electrical enery to the rest of the circuit in order to move the electrons
conductors: componets that transport electrical energy from the power source to the load devices ;in other words , electic current flows through these components.

light: we can convert electricity to light through load devices such as incandencent lamps,fluorescent tubes and electronic or low energy lamps
Heat:When electrons move through a conductor or load devices, they create friction with the material as they pass through, which produces heat.This effect is known as the joule effect
Motion:We can also convert electricity to motion using a motor.the effect obtained when we make an electric current flow through a motor is that its shaft turns in a rotary motion this type of energy is used in washing machines and in drills
sound: we can use electrical energy to transmit sounds through microphones and we can produce sound effects through silence , buzzers and bells .

of the many activities we do every day, the majority use electricity .the production, contains transportation and consumption of electricity all have an impact on our enviroment to varying degrees.
when we save energy ,we save money too more but imprtantly , we save natural resourcess and help to protect the enviroment . this is why we need to consume responsibly and only use the energy we need and always in moderation .
use certain domestic appliances (like washing machines , tumble dryers , dishwashers , etc)
replace old electrical appliances with more efficient ones(that consume less energy) labelled class A.
-
Always switch off electronic equipment instead of leaving then in standby mode, which continues to consume energy.
-
enviromental impact of energy production and transmission:
electrical energy is generated industrially in power stations , which convert a form of energy (chemical ,mechanical , thermal, light ,etc)
many power stations have an impact on our enviroment because they pollute the atmosphere
