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.
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.
How do you show that electric current causes magnetism?
Put a wire carrying an electric current near a compass and it causes the needle to deflect.
What causes a electric current in a 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 causes a electric current?
when a negative and a positive charges attract. or when there is a closed 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.
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.
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.
What makes an electric cuchi?
An electric current relies on several things. First, there must be a continuous connection of conductors. Then there must be a voltage or a potential difference between two parts of a circuit. It is the voltage that causes electrons to move, so generating an electric current. The amount of current depends on both the voltage and the resistance of the circuit. The higher the voltage, the greater the current. The higher the resistance, the lower the current will be.
What causes electric current to keep moving?
What causes an electric current to keep moving is a steady supply of electrons.
