How much electricity does a cell phone use to charge?

The easiest way to determine this is to look at the charger. On the transformer, there will be either a label or imprinted lettering that tells you what the input (meaning from the wall socket) is. Since most phones nowadays charge even while plugged into a USB port, that implies that the transformer is producing only 5 V DC at about 0.5 amps. As such, that means that at 125 V AC, the amount of power that is actually converted to 0.5 amps for the DC side is only about 0.02 amps from the AC side. Of course, there is some power lost during the conversion process, so that means that, for the sake of argument, the amount of power is actually used from the AC side is only around 0.1 amps, so about 12 watts of power. Thus, if you left your phone plugged into the charger for about 3-1/2 days, it would use about one kilowatt-hour of power. On average, that would be about 13 cents of your electric bill (including taxes and other fees).

How do mobile phones work?

Answer

Mobile telephones are two-way radios. When you talk into a mobile telephone, it picks up your voice and converts the sound to radiofrequency energy (or radio waves). The radio waves travel through the air until they reach a receiver at a nearby base station. The base station then sends your call through the telephone network until it reaches the person you are calling.

When you receive a call on your mobile phone, the message travels through the telephone network until it reaches a base station close to your phone. The base station then sends out radio waves that are detected by a receiver in your telephone, where the signals are changed back into voice or data.

How did the cell phone impact America?

The invention of the telephone made a very big change in the Americas. For one, people no longer had to wait for responses to a telegram that they may have sent two long and miserable weeks ago. Anyway, the telephone also sped up conversations. If someone needed to talk to someone, they wouldn't have to worry about tracking them down to talk to them face to face. When the telephone, invented by Alexander Graham Bell Elisha Gray, first made its big appearance, people started to buy and buy these expensive items. People never have to send slow telegrams ever again, that is, if A) they can't afford a telephone, or B) their telephone breaks or stops working. I gotta tell you, that would suck to go back to sending telegrams every single second of the day. I mean, who wants that, right? Hope this information helps =))

Where can you find a free cell phone without paying anything?

Yes you can...In most cases the large wireless retailers will require a security deposit ($300.00 - 1000.00 dollars) if you do not have established credit. The other option is prepaid wireless service where each call you make will cost you .12 cents per minute and .15 cents per text message...this is a very costly way to go. An alternative is the company I have service with Apex Global Wireless. They got me set up without a credit check, no security deposit. i have a regular monthly plan on Verizon wireless. it was real easy to get started with them. I was set up fast with my monthly talk and text plan. check out their website...i highly recommend them to anyone that has no credit or damaged credit like i did.
