Devices that converts other energy to Electrical energy and Different kinds of Circuits

Have you ever used or seen batteries ?
If not , you need to live life more dude .

There are devices that produce electricity .
and these are called ..

Cells . [ not human cells ok ? ]
Cells are devices that  produce electrical current by converting chemical or radiant energy into Electrical energy.

Have you ever heard of Thermocouples ?

then dude , nice to see a science geek in my page .

Thermocouples are devices that convert thermal energy into electrical energy .

Now have you seen or heard of houses that are solar powered , 

Do you know how they "solar-powered " their houses ?

It's because of the solar panels right ? usually these things are attached to their roof, well these panels is just an example of :

Photocells , these Photocells are devices that converts light energy into electrical energy.

Now why are these changes possible ? 

first and for most do you remember ,my previous blog about " The Law of Conservation of Energy " ? 

That no energy is lost but just changed into another one . 

In the same time Electrical energy can also be converted into different forms of energy . 

the rate at which this energy is converted into another is called Electric Power .

Circuits 

Have you observed the lights in your house ?

If you turn the switch on how many lights usually turns on ? 

well , this depends on what kind of circuit you house has .

Have you ever wondered when your mother plugged your christmas tree lights on , all of the lights flicker together at once ..?
That's because Christmas lights are in the so-called Series Circuits '
Series circuits are circuits in which all parts are joined in a single loop , therefore of you turn the switch on all the lights will turn on .

the other kind of circuit is the Parallel Circuit
Parallel circuit is a circuit in which the parts are joined in branches such that the potential difference across each part is the same .



Well then this is the end of the blog for this week ,
just remember ...


Science is beautiful ,
Laziness to learn it is Ugly .


So what do you wanna be ?
Beautiful ? OR Ugly ?

Your choice ! farewell for now Amigos and Amigas !
