An ammeter is used to measure an electric current. Alternatively, you can use a multimeter , set to an appropriate current range.
An ammeter, either shunt or inductive. A shunt is an inline resistor of a small, known resistance. Knowing the resistance and the voltage one can calculate the amperage by Ohms law, I=V/R. An inductive, or clamp on ammeter measures the magnetic field and using more complex calculations displays the …current, typically on a digital display. (MORE)
It is mostly convention. However this produces conflicts with theconventional mathematics usage of i as the square root of -1 incomplex numbers, so in electronics the convention is to use j asthe square root of -1 instead when working with complex numbers inthe analysis of AC circuits.
Currently my mom is sure that I can go on the 5th Grade Field Trip
Convection current is a stream of fluid propelled by thermalconvection. Convection is mostly around gas and liquid
The history of electrical study is a long an varied one. Because of this, many conventions used when describing electrical phenomena seem archaic or just plain weird. This particular oddity, using the letter 'I' to represent an electric current is courtesy of Georg Ohm  the father of the famous '…Ohm's Law'. Ohm was describing the relationship between resistance, voltage and the Intensity of the electric current . We get the I from intensity. In retrospect, this is ironically fortunate because it saved us from having to later, choose an 'odd' letter to represent Capacitance.  Wikipedia: Georg Ohm http://en.wikipedia.org/wiki/Georg_Ohm  IEEE History Center: FAQs http://www.ieee.org/web/aboutus/history_center/bitsbytes/faqs.html. The origin of "I" is "intensite", the French word for "current", as Ampere was French. (MORE)
If the question means "What does electricity do for us?" then we could mention lighting, heating, cookers, refrigerators, telephones and cellphones, radios, TVs, computers for a simple start. If the question seeks to differentiate between electric voltage and electric current, then voltage is the… measure of the energy of an electric charge and current is a measure of the flow of the charge.

It is current. Because current electricity has moving charges while static electricity has stationary charges.
A switch basically represents a gap in the electric circuit. Electric current can pass through a circuit only if it is complete. An incomplete circuit can never pass a current through it. When the switch is in the 'off' position, the circuit has a break (gap) in it. When you put the switch in 'o…n' position, the circuit wire join and the circuit gets completed. (MORE)
Every conductor of electricity creates a magnetic Field when electricity flows through it. What we need to do is create a focus. We do this by wrapping our wire around a piece of iron, a nail or a steel rod works good. You have just created an electromagnet.
An Ammeter is used to measure electrical current, which is measured in Amperes (or Amps).
I wonder what my current location is? or if you are talking about a electrical current Watch out, there is an electrical current in that plug and you don't want to get shocked.
Strictly speaking "current" is not stored ... unless you want to talk about modern, superconducting magnets.. What we're able to store, move from place to place, and use when we want it, is either electric charge, or energy in some other form that can be converted to electrical energy.. Charge can… be stored in a capacitor or a Leiden jar. If you haven't heard of these, that's because these are not effective ways to store useful amounts of electricity for useful lengths of time.. Energy can be stored for later use in batteries or springs (on a small scale), or in water raised and stored high off the ground (water towers and hydro-dams on larger scale). (MORE)
no direct current is not used in transformers. the reason is that, if dc is used, there would be no counter emf to oppose it in the primary winding. since the constant flux will be flowing in the dc, there would be no rate of change of flux. as a result, the total current will be applied at the pr…imary winding only. this results in the burning of the total primary winding. ===== The practical application is: If transformer input is DC, transformer output is smoke.

Electric power is used to operate household appliances. How much was the electric bill last month?
A thermistor could be used to measure temperature, because its resistance is a function of its temperature. By the same reasoning, a thermistor could be used to temperature compensate a circuit. The best example of this is in the regulator, where the ambient temperature controls the charge voltage…, because charge state in a battery is a function of temperature. (MORE)
That depends, on the basis of what you want to calculate it. Quite often, Ohm's law is used: voltage = current x resistance.\n
Current is a simple descriptor, I was taught to always use it in school as leaving it off was an error. For instance you cannot say A for AC (Alternating Current) as A is amperage.
Be sure to turn off the lights because it wastes a lot of electricity and will cost a fortune if you do it too often
because static electricity cannot be controlled or manipulated like current electricity (think of the saying "lightning doesnt strike on the same place twice")
What will you charge me to replace the electrical outlet? The ignition system is based on electrical engineering theories.
The easiest way to answer your question is to point out that every device you own or use, which you plug into the wall or which contains a battery, makes available to you some use of electrical current. Whatever you use each of those devices for is a use of current electricity.
Electricity has been found to be the best thing to use for an electric current.
I can give you several sentences. . The currents in this area are dangerous. . The river's currents will float you gently down to the campground. . If you can find the right air currents, the balloon can travel for hundreds of miles.
It is transformed into energy thus causing heat, but the electricity won't go anywhere, remaining inside the wires on the form of electrons when not flowing. When any electric device is turned on, the electricity begins to circulate again within the circuit.
Electrical current is measured in Amperes which is abbreviated toamps. When dealing with formulae the letter I is used to representcurrent, for example: Power = Voltage Ã Current = volts Ã amps = V Ã I Small currents in electrical engineering use the lower case i; thiscan cause confusion… with the lower case i that mathematicians usefor â-1, so they use j for â-1 instead.

It doesn't make any sense, but I'd say 12 v? === Most electronics use direct current. Direct current is what you get from a battery. The electricity that is delivered to your house and accessed via wall sockets is alternating current. It is called alternating current because unlike direct …current which flows directly in one direction, alternating current alternates directions at a frequency of 60 times per second in the U. S. and 50 times a second in Europe. Most electric motors use alternating current. Electronic devices and chargers have a box, usually built into the plug or sometimes along the power cord, that contains a device to change the alternating current to direct current. ===== The reason alternating current is delivered to houses is: The loss of energy in the cables and wires that carry electricity is less when it's transported at higher voltage. So the electric companies move it around the country, between cities, and from the power generating plants to your neighborhood, at very high voltages, and then step it down just before it enters the houses on the block. To change voltage up and down at various points in the process, transformers are used, and transformers only work with alternating current. (MORE)
No, if it is ever, "Used up" then that means that there is no more flow of electrons. That in turn would mean no electric current is flowing. From Ohm's Law V=IR we get I=V/R. So no matter how large of a value R can be (using resistance equivalence we can make it very large by putting a bunch of res…istors in a row) the theoretical value for I is never zero, albeit very very small.

Here are a few examples... - The electrical current is monitored. - The current of electricity is measured in volts. - The electrical current of telephone wiring is 82 volts. They may not be worded the same, but they have the same initial meaning.
You could use it as , Do you know the must Current Events on the news?
Yes - CRT TV's and monitors do just that - using magnetic deflection to send the electrons to the screen to give an image.
If you have solar panels electric will travel through it so that we can do different things that use electric.
We're deeply intrigued to know where the questioner resides, and from what experience this question arises. We know of no location in the world, and no small-scale situation, where direct current is preferred for the mains supply.
Here is an example sentence with the word "electrical": Electrical appliances should be turned off when not in use in order to save energy.
The transmission of electrical energy requires very high voltages (for a given load, the higher the supply voltage, the lower the load current). To increase/reduce these voltages, you need transformers. Transformers are AC machines; they do not work with DC.
What is difference between positive current and negative current which current is used for generation of electricity?
Positive and negative are just directions. In AC the current changes direction 60 times a second. It is all the same.
60 Hz in the Americas except Argentina, Saudi Arabia and part ofJapan, 50Hz in Europe, Africa, the rest of Japan, Argentina, Russia, theFar East and Oceania.
The word "electrically' can be used as an adverb in a sentence. The game console is electrically running. This new automobile is electrically driven.

A magnetic compass can detect current, but you'll need an Ammeter to measure it. A galvanometer can detect current ~ but you'll need an Ammeter to measure it.
The "north Atlantic current" is very strong. . I really like the "north Atlantic current." . The "north Atlantic current" is driven by the global thermohaline circulation (THC), it is wind driven
A voltage , or potential difference , is what causes current to flow through a circuit. So all devices (called 'loads') require a voltage applied to them.
The word currently is an adverb but the word current is and adjective. It means happening now. The word currently should be used when writing in the present tense. Example "He is currently walking down the road." Remember the adverb must always come before the verb.
Anemometers, employed for measurement of wind speed, often take thefamiliar form of the spinning cups or a propellor-like windmill,but can indeed also use electrical current as one measurementmethod.

Yes. As a matter of fact, a common electronic component called a capacitor works because of this very principle.
Only a DC motor uses direct current, and the reason is that it isthe only supply available. There are also plenty of AC motors used when there is an AC supply. DC tends to be used for low-power devices like fans in electronicequipment.
