Why is it important to use electricity wisely?
In today's culture, electricity is a vital part of functioning as a society. Simple tasks, such as waking up at a designated time or enjoying a piece of music, are accomplished currently via electronic means. One only needs to consider the consequences of a relatively short power outage – factories close down, phones and computers go dead, traffic slows to a crawl, food spoils in refrigerators – to accurately observe how power-dependent our society has become. However, electricity is a constantly developing technology, and the aspects one currently associates with electricity and electricity generation are nowhere close to the original features. In the past century and a half, electricity has steadily evolved from a scientific curiosity, to a luxury of the affluent, to a modern need. Along the way, it has been shaped by a variety of non-technological factors: economic, political, social, and environmental, to name a few.
What inventions came about because of radio?
the telegraph and the telephone, came from the radio all three technologies are closely related, because they use "wireless telegraphy" There are probably many more just look up all the inventions of Nikola Tesla. He has over 50 Patton's in the US and Canada alone
+++
And the Television and Radar! Both are particular types, or rather applications, of radio.
Any Bluetooth headset is compatible with the PS3. <<< NO!!! THIS IS WRONG!!!>>
u actually need a special headset that clearly says ps3 capible, some headsets will play havok with ur wireless controllers!!!!
try Wikipedia I'm pretty sure ps3 is compatible with most headsets.
Electromagnets are created using what?
An electric current flowing in a wire creates a magnetic field around the wire. To concentrate the magnetic field of a wire, in an electromagnet the wire is wound into a coil, with many turns of wire lying side by side. The magnetic field of all the turns of wire passes through the center of the coil, creating a strong magnetic field there. A coil forming the shape of a straight tube (a helix) is called a solenoid; a solenoid that is bent into a donut shape so that the ends meet is called a toroid. Much stronger magnetic fields can be produced if a "core" of ferromagnetic material, such as soft iron, is placed inside the coil. The ferromagnetic core magnifies the magnetic field to thousands of times the strength of the field of the coil alone. This is called a iron-core electromagnet.

A ceiling fan is a type of propeller and also a mixer. The fan is usually composed of flat blades which are attached to an electric motor. The motor,most commonly, has several speeds and can often be operated in a clockwise direction or counter clockwise direction. The fan blades are normally positoned at an angle to the verticle axis of the motor. The result of the angled blades turning is that air will be gathered by the leading edge of the blade and forced to the trailing edge and a breeze is felt coming off of the trailing edge. Withinan enclosed environment such as a room in a home or business,the ceiling fan can be used to accelerate the distribution ofwarm or cooled air within the defined space, reducing energy bills and improving comfort.In the winter, when a warmer interior is required, it is generally considered the most effective operation of the ceiling fan is to"push" the airup toward the ceiling, the loweredge of the blades will be leading as the blades circle. The fan will compress the warmer air in the ceiling forcing it to desend down the walls and pull the cooler floor air up, thus mixing the air within the room and balancing temperature floor to ceiling, creating a more comfortable climate and reducing energy cost bymoving the naturally convected warm air in the ceiling into the living space. The fan operating in the "up" mode also reduces drafts. Because the temperature within the room is the same due to mixing, the controling thermostat will be reading the actual room temperature, not just the stratified temperature at its mounted height.For cooling the opposite applies, the fan should turn with the upper leading edges leading as the blades rotate, causing the air to be blown down, this will pull the hotter air in the ceiling into the cold dense air on the floor and mix it, again balancing floor and ceiling temp, the fan is "pushing" the air down and causing drafts, moving air has a cooling effect on the body, by promoting evaporation. A ceiling fan operating by itself blowing air down will provide some relief on a hot day. A ceiling fan operaing in conjunction with an air condintioner will reduce the run time of the AC unit and allow higher temperatures to be set because moving air is "cooler" than still air.

Can a TV purchased in Australia be used in the UK?
Yes it will. Sweden uses the same voltage/frequency as the UK (230v/50Hz). However - in order to view TV channels in the UK - you will need a digital set-top box for digital television. All the old analogue transmitters are now switched off.
When and why were speakers invented?
First the headphone was developed. Than a headphone capsule was put upsode down on a saucer with a little distance. That was the first loudspeaker.
Scroll down to related links and look at "History of loudspeakers".
What is the advantage of having a refrigerator?
A refrigerator lets a person preserve perishable food, such a meat, vegetables and milk
for much longer periods than are otherwise possible. Refrigerators also have a freezing
compartment that will keep frozen foods frozen and make ice to use in beverages. The advantages of having a refrigerator also include
* not having to make daily trips to the market for perishables * longer storage of infrequently used items * leftovers can be saved for future use * protection against pests
Simply put, 1.6 Amps, or for that matter any number of Amps (which is current), has nothing in and of itself, to do with Watts (which is power).
In any circuit, there are three fundamental units of electrical properties - voltage (E), current (A), and resistance (R). In addition, there's the related unit of power (which are Watts[W]). In any circuit, knowing any two of the four will allow determining the third and forth. The fundamental rule used is called "Ohm's law" which states that the voltage across any circuit is proportional to it's resistance, and the current through it and is usually written as:
E = I x R or simply E = IR
One important detail is that V is commonly used instead of E. So E = I x R is the same as V = I x R. But using "E" is more proper (and stands for the formal name for voltage, "electromotive force" also sometimes abbreviated as "EMF").
One other essential equation is W = I x E.
Using these two equations will answer your question but you must have at least one more unit in addition to Amps, either power, resistance, or voltage.
Without knowing another unit in addition to your current of 1.6A, the question cannot be answered.
As an example, let's take a 100W light bulb which runs on 120V.
Using the relationships shown above, we can calculate that for this bulb, it's current is I = W / E = 100W / 120V = 0.833A.
It's resistance then, is E / I = 120V / 0.833A = 144 Ohms.
So given it's power (W) and voltage (E) we have all four quantities:
E = 120 Volts, R = 144 Ohms, I = 0.8 Amps, W = 100 Watts
Note that combining and rearranging the two equations for E & W (this requires pretty basic algebra and won't be detailed here. Just the equivalent equations will be shown), it can be shown that any two values can be used to derive all four. All the combinations are thus:
Given I and W:
E = W / I = 100W / 0.833 Amps = 120V and,
R = W / I^2 = 100W / 0.833^2 = 144 Ohms
Given R and W:
E = SQRT(W x R) = SQRT(100 x 144) = 120V and,
I = SQRT(W / R) = SQRT(100 / 144) = 0.8333A
Given E and R:
W = E^2 / R = 14400 / 144 = 100W and,
I = E / R = 120 / 144 = 0.8333A
Given E and I:
W = E x I = 120 x 0.8333 = 100 Watts and,
R = E / I = 120 / 0.8333 = 144 Ohms
Given I and R:
E = I x R = 0.8333 x 144 = 120V and,
W = I^2 x R = 0.6944 x 144 = 100 Watts
What parts are needed to create a circuit?
A basic electrical circuit needs a voltage supply (battery or household outlet), wiring to carry electrons to and from the voltage supply to the load, and a load (motor, light, heat element, stereo, blender, whatever).
What is the function of emitter bypass capacitor in common emitter amplifier?
The emitter bypass capacitor in a common emitter amplifier will have less resistance as the frequency increases. Since gain in this configuration is collector resistance divided by emitter resistance (within limits of hFe), the gain will thus increase for higher frequencies, making this into a high pass filter.
Who invented the walkman radio?
=The Radio was around long before the walkman, The radio was out during WWII and earlier and the walkman only came out in around the 70's so if i am correct that is after the good old radio!=
What are all the organs systems in the human body?
The systems are:
Endocrine (hormore/chemical management)
Integumentary (fancy word for skin)
Excretory (how your body removes waste)
Reproductive (how you reproduce)
Skeletal (bones)
Muscular (muscles)
Circulatory (circulates blood & other nutrients needed)
Respiratory (how you breathe)
Nervous (signals from your brain telling you what to do)
Immune (fights diseases)
I believe that is it.
On super Mario 64 ds how do you rescue Luigi?
kill the big boo in the backyard of the castle(mario needed), to go to boo's mansion,go in the front door,go to the 2nd floor(if you have not gotten go on a ghost hunt just triple jump up),go in the door on the back right,go on the table and get the power flower and float up,go in the luigi painting, then go in the doors in this order,right,left,right,left,goacross the falling blocks,up the platforms,and in the hole,and then ground pound or punch the ghost 3 times then you get the luigi key.

Where can one purchase a green laser pointer 100mw?
You can buy cheap laser pointers online. Here is the reason: There are thousands and thousands of people searching the web for brighter, more powerful, and cheaper lasers of all colors every single day. The internet can pretty much take all of the credit for allowing this global industry to grow so rapidly. When you can connect laser manufacturers from China and Japan to distributors in the United States, the UK, Canada, and Australia; you can expect loads of people to get their hands on powerful laser pointers. Then you can see more choice for you on the internet!

Will a red laser light pointer damage a plasma screen?
Only the remote reciver since it will give conflicting information to the tuner/main processor to do wierd things. Might even make the unit's boards faulty at best.
How many lead acid batteries need for storage of 12 volt?
Not all 12 volt batteries actually use acid. Lead/acid storage batteries do, however, and in those the acid is generally 4-5 molar sulfuric acid. "How much" acid depends on the volume of the battery ... some batteries are physically larger than others ... but for a rough figure you can assume that somewhere around 30% of the liquid by mass is sulfuric acid.
What happens when you bring two magnets together?
Well it depends if you have 2 alike sides then they repel but if different they attract
How do you hook up two 12 volt batteries to get 12 volts?
Assuming both batteries are alike in voltage, and preferably current:
For twelve volts, connect the negative to the positive of the other. That will be a series connection, and then use the open negative and positive connections for 12 volt operation.
For 6 volts, but twice the power, connect the positive to the positive and the negative to negative, and use this combination for six volt operation but twice the available current.
NEVER, NEVER, NEVER connect two batteries together with one's positive to the other's negative and the negative to the other's positive. Results? BOOOM!!!!! (And I'm not joking.)
Is Vizio a quality brand television?
They are not a High end brand name, but are built very durably. I have three vizio's in my house along with relatives having many more. High quality picture sound comparable to brand name Sony and Samsung. If you were faced with a decision and were uneasy about vizio, they are not easy to break and will last.
How does a hydroelectric power plant produces electricity?
hydropower is made by water from water dams an proccessed by i think machines. some one please write a logical answer because i need to know this for a science project!!!
ok ok. hydropower is made by dams moving water. they have a spining thing, which is called turbines, at the bottom of the dam that spins when water moves past it. that creates power or electricity, i think. so yea. the faster the turbines spin the more power it produces. i hope that helps
