Is it true that Electrons were discovered when an electric current was passed through gases at low pressures?

Yes, Sir J.J.Thompson did exactly that. ( although at that time the terms used for these phenomena were different). In 1897, Thompson heated a metal to produce cathode rays or electrons. These electrons were attracted towards an anode by providing a potential difference between the two electrodes. Between the cathode and electrode was air at very low pressure which did not stop these cathode rays. Sir Thompson studied these beams in the space between the anode and cathode.

The flow of electrons through a conductor is called?
electric current
Can moving electrons through a magnetic field can produce an electric current?
Electrons moving is an electric current. An electric current moving at an angle to a magnetic field will produce a Force.
Is a electric current a matter or a energy?
Mainly energy. Note that the electric current involves movement of electrons or other particles that are matter; however, the electric current "is" not so much the electrons (they exist whether there is a current or not; it is more precise that the current "is" the electrons' movement. Although even this may be an over-simplification.
What is a steady flow of electrons?
Electric current
What is electrons contribution to electricity?
flow of free electrons produce electric current
What does the electric current have?
In metal conductors, electric current is the flow of electrons.
The flow of electrons through a conductor is called?
electric current
Can moving electrons through a magnetic field can produce an electric current?
Electrons moving is an electric current. An electric current moving at an angle to a magnetic field will produce a Force.
What constitute electric current?
electrons
What is connects the electric current?
it is nothing but electrons of atoms of that element that connects the electric current.
In a circuit electric current is flow of?
It is a flow of electrons.
What subatomic particle is most directly related to current electricity?
Electrons are mostdirectlyrelated to electric current. (Electric current is caused by the movement of electrons between atoms.)
What is a current electricity?
An electric current is the amount of electrons per unit time or seconds.
What does electric current like?
The electric current is a continuous flow of negative charged particles - electrons.
What is electric current and how is it measured?
if you are mesering its presure it is volts
Explain free electron concept and electric current?
the flow of electrons in semi conductor is called electric current. the electrons revolved around the nucleas is called free electrons
