What is the direction of conventional current in an external circuit?

The conventional direction of current flow in a DC circuit is from positive to negative. In reality the electron flow is from negative to positive. Most electronic schematics today still use the conventional current flow when drawn.

∙ 12y agoBy current direction, we mean the direction of current in an external circuit, not within a voltage source.
In metal conductors, current is a flow of electrons which takes place from a negative potential to a positive potential. But in fluids, current may be a flow of charged atoms, called 'ions', and these may flow from a positive potential to a negative potential.

A circuit carrying current in one direction is called a?
Direct current circuit.
What does a commutater in an electric motor do?
It (1) provides a means of connecting a rotating coil to the external circuit, and (2) it is a rotating switch which ensures that the direction of the current through the coil always acts in the same direction relative to the magnetic field in order to ensure its torque acts in the same direction.
What is reversing key related to physics experiment?
a reversing key is used in the circuit to reverse the direction of current in the circuit.
What is the difference between DC and AC?
The primary difference between DC and AC is the direction of current flow. In a DC circuit, all electron current flow is in one direction. In an AC circuit, current flows in one direction for part of the time, and in another direction for another part of the time. In the AC circuit, we'll see current flowing "back and forth" instead of the unidirectional current flow we find in a DC circuit.DC is "Direct Current", and AC is "Alternating Current". In DC, the current flow is in one direction only. In AC, the current flow is constantly changing direction.An example of DC is the output of a battery. An example of AC is the power present in a home electrical system.The current whose magnitude and direction remains change called as alternating current.The current whose magnitude and direction remain unchanged called as d.c. Current.
How does current flow around a circuit?
current in a circuit will flow in a unidirectional manner and when it passes through a resistor in the circuit it opposes its direction
What is the difference between electronic current and conventional current?
Difference between conventional current and electric current? • Electric current can be either negative or positive, but conventional current is always positive.• The conventional current for an electron flow is positive, whereas the electrical current is negative.• For a flow of positive charges, both the electric current and the conventional current are the same.• Since almost every electrical circuit uses an electron flow, it can be safely stated that the conventional current = - electrical current.• In conventional current, the flow of electrons is assumed as a flow of protons on the opposite direction.
Where does conventional current start flowing from?
Conventional current starts from the positive terminal of the power supply, ventures forth to do its business throughout the associated external electrical circuit, and eventually returns to the negative terminal of the power supply to end its journey.
What is the direction of flow of current in a cell?
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.

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).
What is the direction of current in the circuit?
Circular,,,from the word circuit.
How does the flow of current within the simple cell differ from that in a copper wire?
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.
A circuit carrying current in one direction is called a?
Direct current circuit.
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.
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.
Do electrons flow in only one direction?
Yes. Electrical current only flows in a closed circuit. If it were an open circuit, there would be no current.AnswerAn interesting question. The answer is.... not necessarily! I say this because a capacitor is an open circuit, yet it allows d.c. current to flow for a short period of time (while it charges), and it allows a.c. current to flow continuously.
What is the conventional direction of electric current?
from the more positive point to the less positive point in the circuit
