The ELECTRONS flow from the negative to the positive terminal. But it is considered that the electric current flows from the positive to the negative terminal.

Why flow of current from cathode to anode still the flow of electrons is from cathode to anode?
The direction of current, according to convention, is the direction opposite the direction of electron flow. Remember that the anode is where oxidation occurs, so electrons are lost by the anode. These electrons then move from the anode, to the cathode by a wire that usually connects the two compartments. To reiterate, the electrons flow from the anode (site of oxidation) to the cathode (site of reduction). Because electrons flow from anode to cathode, by convention the direction of current is from cathode to anode (the direction opposite the flow of electrons). Hope this helps!
Is silicon rectifier a good conductor or good insulator?
It's a good conductor of current flowing in one direction, and a good insulator when current tries to flow in the other direction.
What allows electrons to flow between electrodes in an electrochemical cell?
The difference in reactivity between two metals is what causes the electron flow, or voltage. It is facilitated by setting up a Galvanic cell, with two electrodes in solution connected by a copper wire (for electron flow) and a salt bridge (for balancing charges between electrodes.)
Electric current is sometimes incorrectly defined as simply a flow of electrons What is wrong with this definition?
Electric current is the rate of flow of electrons.AnswerA more accurate definition of electric current would be that it is a flow of electric charges. While current flow in a metallic conductor is, indeed, a flow of electrons, in other conductors -such as electrolytes- current flow may be a movement of ions. So, it would be more accurate to define current in terms of charge flow, rather than in terms of electron flow.
What energy is the flow of electrons?
current :))))
When the flow of a current is aways in one direction?
When the flow of current is aways in one direction it is known as direct current.
What direction does current flown an ac circuit?
We have suppose the current flow in opposite to the direction of flow of electron.AnswerA.C. current reverses direction every half-cycle.
Which type of current involves charge flow in single direction?
A direct current involves change of flow in a single direction.
What current that does not reverse its direction of flow?
direct current
The direction of a magnetic field produced by an electric current depends on the direction of the what?
Flow of the current.
The what of an electromagnet is determined by the direction of current flow?
The electromagnet (polarity) is determined by the direction of current.
Why is current a vector?
Current Density describe how charge flow at certain point since current density = I/A and the vector direction tells you about the direction of flow at that point.
What is the direction of flow of electric current in an electric current?
DC current
What is the conventional current flow?
Conventional current flow is the flow of positive charges, or the equivalent flow of positive charges. That is, if what flows is really negative charges (for example, an electron), which flow in one direction, the "conventional current" flows in the opposite direction.
In what circuit does the current flow in one direction and then in the opposite direction?
on a three way switch.alternating current.
What is the direction of current due to flow of electrons if it is not conventional current?
Electron flow is from negative to positive. Conventional current flow is from positive to negative.
The expression alternating current refers to which form of energy?
Alternating current is a flow of electrical energy in which the direction of electron flow reverses periodically. The mains electricity in your house is likely Alternating Current. The other form is Direct Current, where the direction of electron flow is in one direction only. Such as the flow from the batteries in your flashlight.
