That's a "direct" current.
Another name for DC current is direct current. It refers to the flow of electric charge in a single direction, as opposed to alternating current (AC), where the flow of charge periodically reverses direction. DC current is commonly used in batteries and electronic devices.
An ammeter is a measuring instrument used to measure the electric current in a circuit. Electric currents are measured in amperes (A), hence the name
Direct current is constant - always in the same direction. Alternating current regularly changes direction; for example, in household current, 50 or 60 times (that is, full cycles) in every second.See the Related Link below for more information about the difference between alternating current and direct current.
In metal conductors, an electric current is a drift of free electrons from a negative to positive. Period! 'Conventional' current (positive to negative) is, as its name indicates, nothing more than a convention -based on an assumption made before the true nature of electricity was determined. In other words, it doesn't exist! So no experiment can 'prove' that conventional current exists because it doesn't exist! The direction of conventional current was based on the assumption, by the likes of Benjamin Frankin, who assumed that an electric current was some sort of fluid which, of course, would flow from a high (positive) pressure to a low (negative) pressure. The discovery of the structure of the atom confirmed that a current (a flow of electrons, in metal conductors) flowed from negative to positive. Think of it this way. When you look at a led display in a waiting room ('take a ticket'), are the illuminated leds moving to the right, or are the unilluminated leds moving to the left? Think of the illuminated leds as electron flow, and the unilluminated leds as conventional flow.
FET stands for Field Effect Transistor. The name FET comes because the gate current of a field effect transistor is zero and current present in the source conductor is due to an electric field produced by the substrate material placed between the gate and the source.
Direct current (DC) is the name of the electric current that always flows in the same direction. It is commonly used in electronics and power transmission systems.
Ions are the particles that move when current flows through a solution. They carry electric charge as they migrate towards the oppositely charged electrode.
The "Circumpolar Current" is the longest ocean current in the world and flows in an easterly direction.
Another name for DC current is direct current. It refers to the flow of electric charge in a single direction, as opposed to alternating current (AC), where the flow of charge periodically reverses direction. DC current is commonly used in batteries and electronic devices.
No river flows southwest through Dublin. The river Dodder flows from the southwest, in a northeast direction and the river Tolka flows in a southeasterly direction.
AnswerElectricity comes from the Greek root word electra, which means "amber." This comes from an observation made by a Greek philosopher, Thales . As he was polishing a piece of amber with a silk cloth, he noticed that it attracted more dust and hair afterward. Hence the name electricity.

Current
currents can be thought of simply by flowing through a wire, though not always the case. It is convenient to think of current density which is the amount of current flowing through a cross sectional area, like water through the opening of a pipe, since electric current flows through many 3-dimensional objects.
The name for the status of a circuit that has breaks which electric current that can't flow is called a Closed Circuit. Electric current cannot flow through an open circuit.
parallel circuit
ampere is the unit in all the systems for electric current
