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 resistors in a row) the theoretical value for I is never zero, albeit very very small.

What gets used up in an electric circuit current or energy?
One of Kierchieff's laws tell us that the more wattage (energy) consumed by an electrical device in a circuit, the larger the voltage difference that exists across the device and the greater the current flowing through it. The energy consumed is directly proportional to the Impedance of the electrical device but is more importantly proportional to the square of the current. WATTS=VOLTS X AMPERES= RESISTANCE (IMPEDANCE) X AMPERES X AMPERES A Circuit with Current but without resistance would exhibit no energy at all.
What are the 4 electrical rubber gloves classes?
Class 0: up to 1000 V, red label, used for delicate work Class I: up to 7500 V, white label Class II: up to 17000 V, yellow label Class III: up to 26500 V, green label Class I,II,II used for all other electrical work
What energy tranformations does a siren have?
It starts out as electrical, then changes to acoustic(because you can hear it) and radiant(because it lights up). It might also later become thermal energy(unwanted energy) if it is on for a long period of time because the light will start to get hot.
What happens when you fold aluminum foil to small piece?
When you fold aluminum foil into a small piece, it can be used to charge a dead battery. The electrical charge is present when it is folded up.
Which energy changes takes place when a pedling cyclist uses a generator to light his bicycle lamp?
There are 2 energy changes that take place in this action: Mechanical to Light Energy and Mechanical to Electrical Energy. To explain further, when a generator, which uses mechanical energy, is used in turn to light up the bicycle lamp, the light emitted is light energy. At the same time, when the generator lights up the bicycle lamp, the lamp is light up using electrical energy, so mechanical energy also transformed into electrical energy. ===============================> heat and light (in the light bulb)
Where are transforers used?
Most electrical transformers are used to step up or step down the voltage of alternating electrical current.
How is current electricity used by humans?
Current electricity is used by many humans. It's used to power things up such as, lamps, games, electrical devices and more.PEACE!!!!
What is an electrical capacitor?
Electricity is either alternating current or direct current, abbreviated AC or DC. An AC/DC Capacitor can be used in either an AC or DC current.
How electromagnets are used in speakers?
An electromagnet is used to convert electrical signal to speech signal. It is made up of a metal coil which produces magnetic field when current is passed.
Is a toaster current or static electricity?
A toaster uses electrical current to generate heat and toast bread. So, the electricity used in a toaster is in the form of electrical current.
If energy and mass cannot be destryed than what happends to the electrons of used electrical energy and why is this used energy unable to be converted back to electrical energy?
The electrons in an electrical current are not used up by the current. They are simply moved. A simple way to think of the current is as a stream of water, except that in the current it is electrons that are flowing, not water molecules. When the energy in a water current is tapped - by a turbine, say - the water molecules are not destroyed, although the turbine obtains energy.In principle used ("converted" would be better) electrical energy could be changed back into electrical energy, except that some of it will be forever lost as heat. This energy has not been destroyed, merely converted into a form where it can do no useful work. This is an inevitable consequence of the second law of thermodynamics, which applies to all energy conversions, not just electrical ones.
How can radio waves convers to electrical energy?
An antenna picks up radio waves and converts them to electrical current
What may cause an electrical conductor to heat up?
All ordinary conductors have some resistance to the flow of electrical current. When current flows through resistance power is produced and dissipated as heat.
Which property of Electric current is used in electrolysis?
Probably the fact that a typical electric current is made up of moving electrons. Also, the fact that it carries energy.
What is the aluminum wire equivalent to?
In the electrical trade aluminum wire is equivalent to copper wire as it is also used to carry current. To carry the same current as copper wire aluminum wire is up sized to meet the same ampacity.
Why do batterys work?
Regular batteries work because of the electrical current that runs through them. Acidic fruits have particles which when charged up act as an electrical current allows them to work just like a normal battery.
Is it correct to say that an electrical current is used up as it passes through an electrical component?
No. No more than water is used up as it passes through a pipe. In almost all circuits, for every electron that leaves the negative terminal of the battery and flows into the circuit, an electron returns at the battery's positive terminal. Each electron is completely spent, exhausted, limping, semi conscious, completely empty of energy and barely able to stagger to the finish line, but the number of electrons ... the amount of current and the amount of charge ... is not 'used up'.
