The flow of electrons or is it magnetic fields
AnswerAn electric current is a drift of electric charge, due to a potential difference. In metal conductors, the electric charges involved are free electrons, but in conducting liquids and gases, they are ions (charged atoms). The drift is extremely slow, in the range of millimetres per hour.

What causes a electric current in a electric circuit?
Voltage causes current to flow in an electric circuit.
When wires are connected to the terminals of a battery. what causes electric current in the circuit?
The resistance of the load is what causes an electric current to flow in a circuit.
What causes a electric current?
when a negative and a positive charges attract. or when there is a closed circuit.
Why must a circuit be closed in order for current to a flow?
A circuit must be closed in order for a current to flow because it helps keep a current flow pass. When the switch is closed on a circuit there is a constant flow. When the switches open the flow is disturbed around the circuit.
In a circuit the purpose of a switch is to?
In a circuit, the purpose of a switch is to control the current flow to the load by opening the circuit (off) or closing the circuit (on). When the circuit is open, the is no complete loop through which the current can flow. When the switch closes the circuit, it restores the loop, and thus allows the current to flow.
What causes a current in an electric circuit?
Voltage causes current to flow in an electric circuit.
What causes a electric current in a electric circuit?
Voltage causes current to flow in an electric circuit.
What causes an elecrtic current to flow in a circuit?
The movement of electron towards the high potential causes electric current to flow in a circuit.
When the wires are connected to the terminals of the battery what causes electric current in a circuit?
The resistance of the load is what causes an electric current to flow in a circuit.
When wires are connected to the terminals of a battery. what causes electric current in the circuit?
The resistance of the load is what causes an electric current to flow in a circuit.
Corrosion in a circuit results in high current flow?
When there is corrosion in a circuit, it results in lower current flow. This is because corrosion actually causes resistance.
What causes a electric current?
when a negative and a positive charges attract. or when there is a closed circuit.
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.
Why is there no flow of electric current?
There are two possible causes: 1. The circuit has no Voltage applied to it. 2. The resistance of the circuit is INFINITE.
A complete electric circuit includes a voltage source current wires and something to ground the flow of current?
If you ground the flow of current like the last part of your question states you will not have a complete circuit as the circuit will open on a short circuit. To make a complete circuit operate you need a power source, an overload device to protect the conductors of the circuit, conductors to carry the current and a load across the power source which causes the current to flow in the circuit. Leave any one of these things out and you will not have a complete circuit.
What flows through a circuit and causes a magnetic field?
An electric current flowing through a circuit causes a magnetic field. This is due to the movement of electric charges, usually electrons, in the circuit. The magnetic field produced is perpendicular to the direction of the current flow.
Why must a circuit be closed in order for a current to flow?
A circuit must be closed in order for a current to flow because it helps keep a current flow pass. When the switch is closed on a circuit there is a constant flow. When the switches open the flow is disturbed around the circuit.
