Current in an electric circuit is caused by the movement of electric charges, usually electrons, through a conductor. This movement is typically initiated by applying a voltage difference across the circuit, which creates an electric field that pushes the charges. The current flow will continue as long as there is a closed path for the charges to move through.

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.
What causes a electric current?
An electric current is caused by the movement of electrically charged particles, typically electrons, through a conductor like a metal wire. This movement can be driven by a voltage difference or potential between two points in the circuit, which exerts a force on the charged particles and causes them to flow.
What causes current to flow in a circuit?
The flow of electrons or is it magnetic fieldsAnswerAn 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.
An electric current occurs in a circuit when?
An electric current occurs in a circuit when a source of energy (or power, which is energy with a time factor) causes electrons to start slowly moving through the circuit at a speed of a few mm or cm per hour. This allows the quantity that we call charge to race through the circuit at a speed of roughly a million miles per hour, which is what we call electric current. Mathematically defined, electric current is the amount of charge which passes a given point in the circuit each second of time, I = Q/t .The source of energy or power can be as nearby as an energy cell or battery, or can be an electrical generating station located many miles away.

What causes a current in an electric circuit?
Voltage causes current to flow in an electric 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.
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.
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.
What does an increase in voltage cause in an electric circuit?
It causes a proportional increase in current.
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 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 electric current?
An electric current is caused by the movement of electrically charged particles, typically electrons, through a conductor like a metal wire. This movement can be driven by a voltage difference or potential between two points in the circuit, which exerts a force on the charged particles and causes them to flow.
What process by which an electric current is produced?
An electric current is produced through a process called electromotive force (EMF), which can be generated by batteries, generators, or solar cells. When a circuit is closed, the EMF causes the flow of electric charge, resulting in an electric current.
What is the relationship between the electric field formula and voltage in an electric circuit?
The electric field formula and voltage in an electric circuit are related because voltage is a measure of the electric potential difference between two points in a circuit, and the electric field is the force that causes charges to move between those points. In simple terms, the electric field creates the voltage that drives the flow of electric current in a circuit.
If current increases and resistance increases what would cause this?
The only way current can increase while resistance in a circuit increases is if voltage, which is the force that causes electric current, increases.
