it is electron because there are free electrons in a conductor .The atoms are fixed on their places.The positive ion (as a result of emission of an electron which is negatively charged ) remains still on its place and hence the free electrons are responsible for the current flow . In solutions and gases the positive ions can also move because they are free to move unlike in the metal

∙ 15y agoIn a broad sense, the protons in the nucleus of an atom and the electrons in their orbitals about it are all electric charges. The electromagnetic attraction of the different (opposite) charges keeps the atom together. But it is the electrons that are responsible for what we normally consider electric current. Electric current, though it is the movement of any charge or charges, is generally considered to be the movement of electrons, and it is these moving electrons that give rise to the electricity we use every day.

Is current is the rate of electrical flow in a circuit and that votage is the opposition of current flow?
'Electricity' is not a quantity; it's the name of a subject area or topic (just like 'chemistry'). So 'current' describes a flow of charge (not 'electricity'), expressed in amperes. 'Voltage' (potential difference) is responsible for 'driving' current, expressed in volts. 'Resistance' is the circuit's opposition to current, expressed in ohms.
When there is a difference in voltage the flow of charge is called?
flow of charge is called current. but the direction of flow of current is always taken oppsite to the flow of charge.
Which part of a circuit is a current?
Current is the flow of electric charge or the rate of the flow of an electric charge through a conductor.
What is flow of charge?
That is called an electrical current.
Is it true that In Ohms law the variable i represents the rate of flow of charge which is called impedance?
"I" represents the current which is the flow of electric charge. Impedance is the measure of the opposition to the flow of current at a given voltage usually in a.c. circuits.
What name is given to the rate of flow of charge?
Current

What is the name for the flow of electrons in an electric circuit?
A flow of electrons in an electrical circuit is called a current, which is the name given to the amount of electrical charge flowing in a certain period of time.Any total quantity of electrical charge is measured in coulombs.Any flow of electrical current is measured in amps.1 amp is equal to a flow of 1 coulomb of electrical charge in one second of time.
What is the rate of a flow charge?
Rate of flow of charge is called electric current. Generally we knows current means flow.... here rate of flow of charge means how much charge flows in a given time is called electric current
What matter is current?
flow of charge is current
What is current?
Current is the rate of charge flow
Which part of a circuit is a current?
Current is the flow of electric charge or the rate of the flow of an electric charge through a conductor.
Difference between electrical current and electrical charge?
current is the flow of charge.
What is the term of the flow of electric charge?
Electric Current is the flow of electrons and hence charge
In which direction does conventional current flow?
Conventional current is the flow of positive charge (or the equivalent flow of negative charge in the opposite direction; e.g., if electrons move to the left, the conventional current is to the right).Conventional current is the flow of positive charge (or the equivalent flow of negative charge in the opposite direction; e.g., if electrons move to the left, the conventional current is to the right).Conventional current is the flow of positive charge (or the equivalent flow of negative charge in the opposite direction; e.g., if electrons move to the left, the conventional current is to the right).Conventional current is the flow of positive charge (or the equivalent flow of negative charge in the opposite direction; e.g., if electrons move to the left, the conventional current is to the right).
Negative charge on electrons is responsible for?
By moving a stream of electrons, we have an Electric Current. Which is very useful and we can make 'electric light' out of the current flow. Also we can generate a magnetic field with our current flow. Such as in 'electric motors'. We can also use the charge on the electrons to charge up an insulated piece of material. Such as in a 'foil electrometer'. Or in an 'electro static voltmeter', useful for very high voltages. These also respond to the RMS of a voltage.
