Current, measured in Amps, is the movement of electrons within a conductor. In direct current (DC) circuits, the electrons are always moving in a single direction from the minus to the plus.
In alternating current, or AC, the electron flow reverses 120 times each second (in the USA) or 100 times each second (Europe). This is the way electricity is delivered to homes in nearly all of the developed world. Without getting too much into technical details, alternating current allows the use of Transformers which make generating, delivering, and using electric power more convenient, cost effective and safe.
Current is the actual movement of electrons. Other important measures in electricity are voltage, which is potential force, or ability to cause electrons to move. Power, which is energy released and is measured by the current times the voltage. There are many other measures.

What were the earliest types of electricity that scientists experimented with?
static electricity and current electricity
Something that will not let electricity flow through it is a?
Note that "electricity" doesn't flow, only current does, which is one aspect of electricity, does. Current is the flow of electrons. Bad conductor of current, or an insulator.
When you feel electricity run through you when he touches you what does it mean?
He is touching something with an electrical current and has made you part of the circuit.
The difference-relationship between static and current electricity?
In current electricity we discuss moving charges while stationary charges are studied in static electricity.
What elements allow electricity to pass through?
Note that "electricity" doesn't flow, only current does, which is one aspect of electricity, does. Current is the flow of electrons.A circuit lets electricity flow through it.Conductors allow the easy flow of electrons. Conductors are metal, usually copper or aluminum.Note that "electricity" doesn't flow, only current does, which is one aspect of electricity, does. Current is the flow of electrons.Metals are good conductors. They provide little opposition (resistance) to the flow of currentNote that "electricity" doesn't flow, only current does, which is one aspect of electricity, does. Current is the flow of electrons.A conductor lets electrons easily flow in it.
Why do you measure electricity?
You mean the voltage? The electric power? the current? What electricity you mean? Perhaps you mean why do electricity suppliers measure it? To send me the bill of course.
What does the word convection current mean in geography?
it means electricity
What are the two basic types of electricity?
The two types are "static electricity" and "current electricity."
What do mean by 220 volt current?
220 volts means the power behind the electricity. current means the speed at which the electricity is being transmitted. currecnt is measure in amperes.
What do we call the movement of electric charge?
electricity
When a torch is on is it a static electricity or current electricity?
current x
What are the five types of electricity?
AC specifies alternating current and DC means direct current.
What does to allow energy of electricity to flow mean?
It means that you let an electrical current flow. The current will, of course, carry energy.
Do you use static electricity in your homes or current electricity?
electric current (alternating)
What does the term voltage and current mean?
Voltage -the rate at which energy is drawn from a source that produces a flow of electricity in a circuit; expressed in voltsCurrent - a flow of electricity through a conductor; "the current was measured in amperes"
Which is more useful static or current electricity?
It is current. Because current electricity has moving charges while static electricity has stationary charges.
Metal conduct current?
Metal conduct electricity and flow of electricity is the current.
