Question

Can someone please help me?

Answer 1

@Hagopian13 Can you please me?

Answer 2

I'll take a look at it, give me a second.

Answer 3

ok thx :)

Answer 4

I believe the answer is B. the light bulb. I double checked with my friend who is a computer science guy. We both agreed that the phrasing of the question "when it changes electrical energy into other forms of energy" means it is converting electrical energy into light energy.

Answer 5

The only part of the system that would do any converting of electrical energy to another form would be the light bulb.

Answer 6

i believe it a

Answer 7

But the wire is a conductor. An insulator resists the flow of a charge.

Lightning: electricity in nature

Electricity occurs when electric charge flows. It is an energy source which we use to power machines.

We see electricity when the number of electrons an atom has are either more than usual or less than usual. If the electrons stay where they are, the atom that has too many or too few electrons will attract or sometimes repel other atoms. If the electrons move from where there are too many to where there are too few, then we will see a flow of electrons, an electrical current.

There is electricity in nature as well as electricity that is human-made. We see electricity in nature as lightning, and as the way some things attract each other and stick together.

Scientists have found we can make electricity if we pass a magnet close to a metal wire, or if we put the right chemicals in a jar with two different kinds of metal rods. We can also make static electricity by rubbing two things, for instance a wool cap and a plastic ruler, together. This may make a spark.

Scientists have observed that electricity can flow like water from one place to another, either as a spark or as a current in a metal. They now know that all matter has an electric charge, but this is mostly cancelled out by the presence of matter with an opposite charge. We only see an effect when there is too much or too little electric charge in one place so that it is not cancelled out.

Since the nineteenth century, electricity has been used in every part of our lives. Until then, it was just a curiosity or a force of nature seen in a thunderstorm.

People make most our electric energy in generators. The biggest generators are in power stations. Some of our electricity comes from photovoltaic cells or from batteries.

Electricity arrives at our homes through wires from the places where it is made. It is used by electric lamps for producing light, electric heaters to produce heat, etc. It is also used by many devices such as washing machines, electric cookers, etc. for doing work. In factories, electricity is used for running machines and computers.

The people who deal with electricity and electrical devices in our homes and factories are called "electricians".

Answer 9

maybe this helps

Answer 10

Ok so is the answer A Or B?
*little confused..*

Answer 11

maybe if u google it

Answer 12

i have to do something

Answer 13

going to log back in

Answer 14

I am confused to what lightning has to do with a circuit...

Answer 15

:/

Answer 16

I say let's break down the circuit: what do you know about the circuit in question? Just write down what you know.

Answer 17

anyway, do you mind helping me with a another question?

Answer 18

Sure thing.

Answer 19

ok :)
Why would an electrician use parallel circuits to wire the lights in each room of a house instead of using a series circuit?


A.
Parallel circuits prevent electrons from flowing if part of the circuit is broken and therefore prevent fires. Series circuits cause more fires because electrons still flow.


B.
When electricians get their license, they are only licensed to install parallel circuits. Most electricians aren't certified to install series circuits.


C.
Parallel circuits are much easier to wire and are required by the electrical code for housing construction in most communities. Series circuits are sometimes used with special approval.


D.
Electrons continue to flow in a parallel circuit even if part of the circuit is broken. In a series circuit, a break such as a burned out lightbulb would cause the current to stop in the whole room.

Answer 20

it's A

Answer 21

i think

Answer 22

wait a minute

Answer 23

The answer is D, otherwise you'd have to turn on the lights in the kitchen to have your refrigerator work.

Answer 24

ok

Answer 25

That is an example I found online.

Answer 26

Can you please give me a link you found?

Answer 27

Sure thing, it is a wiki answers link though, it was the best example I could find to illustrate the idea.

Answer 30

That link may also help with your original question, too.

Answer 31

Thanks for the interactive link :)

Answer 32

I will admit that I kind of jumped with joy when I saw the link. Those are really hard to come by and have them be good.

Answer 33

yup :)
thnx :)

Answer 34

You are more than welcome!

Answer 35

@DollyAcquah : Regarding: "Ok so is the answer A Or B? *little confused..*

The battery is the source of energy. It provides energy. Normally, the battery in a circuit like this one does not get warm.

However, when electric current flows through a resistor (which is what an electric light bulb really is), energy is converted from electrical to heat and light.

Answer 36

Thank you for the clarification @mathmale !

Answer 37

yup thanks
