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 electric current in a circuit is caused by the flow of electrically charged particles, typically electrons, through the wires. When the battery is connected, it creates a potential difference (voltage) that pushes the electrons to move from the negative terminal to the positive terminal, creating a continuous flow of current in the 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.
What happens to an electric current when a circuit is closed?
When a circuit is closed, meaning there is a complete path for the electric current to flow, the current will flow from the positive terminal of the voltage source through the circuit components and back to the negative terminal. This flow of current allows electrical energy to be transferred and work to be done in the circuit.
How a fuse controls the flow of electric current in a circuit?
A fuse does not control the flow in a circuit, it limits the current in a circuit. If the load in a circuit shorts out the fuse link melts and opens the circuit and stops the current flow and prevents the wires feeding the circuit from melting and catching fire. resist
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.
How does a resistor affect the flow of current in an electrical circuit?
A resistor restricts the flow of current in an electrical circuit by resisting the flow of electrons. This causes a decrease in the amount of current that can pass through the 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.
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.
When wires are connected to the terminals of a battery. what causes electric current in the circuit?
The electric current in a circuit is caused by the flow of electrically charged particles, typically electrons, through the wires. When the battery is connected, it creates a potential difference (voltage) that pushes the electrons to move from the negative terminal to the positive terminal, creating a continuous flow of current in the circuit.
What trips a circuit breaker and causes it to shut off the flow of electricity?
A circuit breaker trips and shuts off the flow of electricity when there is an overload of current or a short circuit in the electrical circuit.
How do resistors affect the change in current flowing through a circuit?
Resistors in a circuit reduce the flow of current by impeding the movement of electrons. This causes a decrease in the overall current flowing through the circuit.
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.
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 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.
