Current means flow.
Electric current means flow of electric charges
Now there are two kind of charges. They are positive and negative
But current is defined as the flow of positive charges
But in metallic wires there is no chance for positive charges to flow through. Only loosely bound electrons with negative charge are capable of flowing. So current is case of metallic wire is due to electrons. So we have to assign as "conventional current". Conventional current is always opposite to the flow of electron flow
Now from a battery current (conventional) flows right from positive polarity to the negative polarity.
But within batter is has to flow right from negative to positive so as to complete the circuit of flow.

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.
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.
Why do batteries only supply direct current?
The nature of the chemical reactions taking place in a battery cause electric current to flow only in one direction.
Is the direction of current through a battery always from negative to positive on the terminals?
Conventional current flow is from positive to negative. Electron flow is from negative to positive
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.
How you can indicate the current direction in the network?
If we go for the diagramatic representation then battery positive is represented by the long terminal and battery negative is represented by the short terminal then the direction of the current is given by an arrow from positive terminal to negative terminal (Therotically electrons flow from negative to positive but we represent current flow from positive to negative. This is the sign convention )
What is current direction?
Outside the battery, it is negative to positive and inside the battery it is positive to negative.
What causes a posite current in a battery?
A electrical from a battery is the flow of elecrons through a circuit in the opposite dirrection to the current flow. This current flow also happens inside the battery between the plates.
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.
What allows current to flow in one direction?
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. ]
What is difference between cell and diode?
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.
How is it possible to measure negative current?
The term, 'negative current' simply refers to the sense or direction of a current compared with an assumed, standard, direction. For example, in the case of a battery, we normally assume that current leaves its positive terminal and enters its negative terminal (assuming conventional flow), and this is considered its 'positive direction'. However, if that battery were to be connected to a battery charger, the actual current would flow in the opposite sense to the assumed current direction and, so, it would be considered to be a 'negative' current.So, the simple answer is, yes, we can measure a 'negative current' by using an ammeter. In the case of d.c., it may be necessary to reverse the connections to that ammeter to ensure that it reads upscale.
