What are the uses of an electric can opener?
A switch, circuit breaker, fuse, or switching transistor can do that.
Eyup mate how ya doing I hope you get D* D* D* in public services and achieve everything you desire in life mate an electric can opener is something you shove up your stinky p…ink starfish after 9 o'clock (PM) mate hope this helps i'll see ya soon buddy
A number of electric can openers are made in the US including the EZ-DUZ-IT and, for heavier duty work, the Edlund 266 (see Sources and related links section below). ANSWER 2…: There is only one electric can opener still made here and it is the Edlund 266. The EZ_DUZ_IT can opener is a manual can opener, not an electric.
How do you use the broiler to cook steaks on electric stoves and should you leave the oven door cracked open a little bit?
Answer Most electric stove manufacturers will recommend that you leave the stove door open when you are broiling. Put the steaks in a broiler that has the slots,… then put the shelf up high enough that the steaks are about 6 inches from the heating element.
Electricity has become a household necessity in many places around the globe. It is used to power everything from batteries in a child's toy to powering NASA's super com…puters. So, why is it useful? It has people bound to their couches watching television. It has people up in the middle of the night instant messaging to friends halfway across the globe. It even has people of all ages glued to iPods, PSPs, laptops and much more. Even so, electricity does have its uses. It powers your ICU machines in the hospitals. It powers the computers of every airline on the planet allowing us to fly safely through the skies without fear of crashing into another plane. It powers the this simple household computer from which I am typing and allows you, where ever you are to ask this question; and me to answer it as best I can. So, electricity is useful.
What uses more electricity - keeping a fridge door open for a while or constantly opening and closing it during this time?
Every time you open your fridge door - or indeed your freezer's door - it allows cold air to fall out onto the floor of the room. If this is allowed to happen for more t…han a few moments the thermostat inside the fridge or freezer, sensing that too much cold air has gone, will turn on the fridge's motor and compressor pump to cool down the new air. The more the compressor pump and its motor are forced to run unnecessarily, the more electricity would be used, with the consequence that the money to pay for that electricity would simply be wasted. Knowing those "facts of life" it should be easy to understand why it is better to keep the door closed as much as possible instead of leaving it to hang open for more than the short time it takes to load or unload food from the fridge.

Electricity has invaded our lives and has become vital in almost all aspects of society today. The list of uses will fill a book but here are a few headings: Trans…port Trains, buses, trams and cars all use electricity. Many use it as the motive power, meaning that electricity drives the wheels to make the vehicle move. Even gas and diesel powered vehicles use electricity to start the engines, control the engine and power the ancillary devices. Home Heating, lighting, television, radio, computer, telephones all rely on electricity. Even wireless lights such as solar powered lamps will convert sight to electricity. Communication As well as providing power for computers, cell phones, fixed phones, electricity is used as the medium for the transmission of signals. Even high speed optical fibers rely on an electrical signal at each end of the line. Without electricity, communication would be reduced to letters, flag waving and lighting fires and shouting at each other. None of the electricity free methods are as flexible as any that we are used to using today Industry Manufacturing relies on electricity to drive virtually every moving part in a factory. Saws, cutters, conveyor belts, furnaces, chillers - whatever the process, electricity is involved somewhere. Entertainment The MP3 player, the portable battery powered radio, memory stick are all accepted as part of our everyday lives. All rely on electricity to operate. Whether connected to a mains supply or battery, they all use electricity. The list is by no means complete. Take a look around you: if it moves, lights up or makes a noise, it probably uses electricity. (pet dogs and cats excluded of course). Come to think of it, even animals and people use electricity for senses and muscle control, so perhaps the pet dog or cat should be included after all!
The device is called a switch.
Electrons cannot traverse or move thru an open circuit. Therefore there is no current or 'electron' flow. Voltage may be present with an open circuit but it is doing no 'work'…. Compare an open circuit with 'potential' energy. Even though potential energy exist there is no kinetic energy unless the electrons have a path to take. An open circuit provides no such path. Kinetic energy means something with mass is moving and in some cases that movement is harnessed to accomplish 'work'. Potential (voltage) which is doing nothing because a circuit is open cannot accomplish any work since there are no electrons moving. Another perspective: If an electric circuit is opened, the electricity flow stops. This is due to the fact that air is a strong insulator, and most amounts of electricity (save for lightning) do not have enough voltage to overcome this resistance (in a process called ionization). This is reflected in a formula V = I × R where r is resistance, i is amperage, and v is voltage. Through this relationship, as resistance reaches a high level, voltage drops, and the electric flow stops because it cannot overcome the resistance with the force of voltage or amps. A thought on the ionization process: As ionization occurs, resistance across the 'gap path' drops and voltage, if not regulated will drop as well. When there is not enough voltage to cause ionization the voltage will be higher than at the time ionization occurs. At ionization, current (I) will increase, resistance (R) will decrease and voltage (E) will decrease as well and the potential (voltage) is now causing energy or electrons to flow. As the ionization occurs much less voltage or potential is required to maintain the ionization path than is required to achieve ionization to start with. Example: A cars ignition coil is capable of producing 45K~50K volts of electricity. Yet when the voltage is measure at the end of the spark plug wire there will be only 9K or 10K volts due to the air/fuel molecules being ionized Not to sure ionization actually is applicable to the original question however. :0) BTW, I'm 'old school' where E=I x R where E = Voltage. Just like megacycles to megahertz, I guess everything changes but the laws of physics.
Thomas Edison patented an electric distribution system in 1880, which was essential to capitalize on the invention of the electric lamp. On December 17, 1880, Edison fou…nded the Edison Electric Illuminating Company. The company established the first investor-owned electric utility in 1882 on Pearl Street Station, New York City. It was on September 4, 1882, that Edison switched on his Pearl Street generating station's electrical power distribution system, which provided 110 volts direct current (DC) to 59 customers in lower Manhattan.

The motor has a coil of wire that is an electromagnet. This causes the motor to spin, turning the fan blades.
Using electricity is a tough thing to conceptualize-we draw it from our sockets to power computers, stereos, and appliances, and it indiscriminately runs our refrigerators, m…icrowaves, and air conditioners. We're even sucking down electricity when our appliances are off, thanks to phantom power. It all amounts to the sapping of resources-whether your electricity comes from coal burning plants or nuclear power-and we could all stand to cut down. Yet it remains a relatively abstract concept, that is, we're never really sure exactly how much electricity we're using-unless we have an ever-useful electrical use calculator on hand (or more accurately, online). Take a look at the calculator on Michael Bluejay's electricity website to find out exactly how much wattage you're using-and how much money it's costing you. Once you've broken down your electrical usage, it makes it much easier to isolate problem areas and cut back. Leave some of your lights on all day or all night? Each one could be costing you around 30 dollars a year. And even though turning off a few lights or unplugging your computer may not seem like momentous acts, if everyone were to do the same, we could relieve some serious strain on natural resources that have already been stretched thin.
