It may not be correct to say that an electric current will "flow into" circuits. Electrons move in a circuit in response to an applied voltage. And these electrons are alread in the circuit and available to support current flow if a voltage is applied.

It may be more correct to say that electrons leave the negative terminal of a voltage source, and electrons enter the positive terminal of that voltage source. The electrons in the circuit that are availble to support current flow will "shift over" to create the current flow. Remember that the phenomenon of current flow in a wire is the "shifting over" of electrons in the wire. It's not about electrons going into one end of a wire and those same electrons coming out the other end.

0Electric current is a flow of electric charge. In electric circuits the charge is carried by moving electrons in a wire.

ammeter is a measurement tool used to calculate the current flow in electric and electronic circuits

In circuits, positively charged particles do not move around. However in the study of circuits, electric current is defined as the flow of positive particles. But electric current is actually the flow of negatively charged electrons.

Circuits are used anywhere you want to have an electrical current flow. Without a circuit, you cannot have current flow. Without current flow, you cannot do any work.

It makes the current bigger

The opposition of current flow is measured in ohms. For DC circuits it is resistance and for AC circuits it is impedance.

In automotive, electrical circuits current is considered to flow from the battery. Most cars will have a 12-volt battery which will provide the electrical circuits current.

Electrons move to the positive pole from the negative pole in an electric circuit. The electric current is a flow of electric charge that is often carried by moving elections in a wire in electric circuits.

"I" represents the current which is the flow of electric charge. Impedance is the measure of the opposition to the flow of current at a given voltage usually in a.c. circuits.

Electric current is the rate of charge flow past a given point in an electric circuit, measured in Coulombs/second which is named Amperes. In most DC electric circuits, it can be assumed that the resistance to current flow is a constant so that the current in the circuit is related to voltage and resistance by Ohm's law. The standard abbreviations for the units are 1 A = 1C/s.

flow of current in an electric circuit.

electric current is the flow of electric charge ;)

electric current is the flow of electrons which is opposite to the flow of holes ie conventional current

An electric flow, is Current. Measured in Amps(Amperes)

The flow of electric charges is current.

The circuits conductor serves as a pathway for current to flow.

it is the flow of electrons

electrons (NOVANET)An electric current is the flow of charged particles.Current is the flow of charge.

In open circuits the path for current to flow is broken. If you turn off a light switch, you are "opening the circuit", current flow stops and the lamp goes out.

In metal conductors, electric current is the flow of electrons.

electric current is actually a flow of electrons.

Electric current

For an electric current to flow, a path is required, where electrons (or other charged particles) can flow. A voltage is also necessary.

Current is the flow of electric charge or the rate of the flow of an electric charge through a conductor.
