Current doesn't flow inside the cell. The cell is used to push current through an external
circuit.
The so-called "conventional" current flows out of the positive terminal of the cell, through
the circuit, and back into the negative terminal of the cell.
The confusing truth is that the actual physical carrier of current is the electron, which
carries a negative charge. So the things that are actually moving and carrying the current
through the circuit leave the dry cell from its negative terminal, physically flow through
the circuit, and end up at the cell's positive terminal.
from positive direction to negative atom to atom.
A "cell" (word for part of a battery) is a source of current flow.A diode is a device that restricts current flow to one direction.
When the flow of current is aways in one direction it is known as direct current.
One terminal of a cell or battery is positive, while the other is negative. It is convenient to think of current as flowing from positive to negative. This is called conventional current. Current arrows in circuit diagrams always point in the conventional direction. However, you should be aware that this is the direction of flow for a positively-chargedparticle.In a copper wire, the charge carriers are electrons. Electrons are negatively-charged and therefore flow from negative to positive. This means that electron flow is opposite in direction to conventional current.
We have suppose the current flow in opposite to the direction of flow of electron.AnswerA.C. current reverses direction every half-cycle.
A direct current involves change of flow in a single direction.
direct current
A diode is one of the fundamental building blocks of electronics. They allow the flow of electrons in one direction only. Thus are commonly used as rectifiers to turn ac voltages into dc. [A dry cell (mistakenly called a battery, which is a group of cells) will allow electron flow in one direction only, or rather, it will provide current flow in one direction. ]

Flow of the current.
The electromagnet (polarity) is determined by the direction of current.
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.
