What causes an electric current?

An electric current is caused by the flow of charged particles, typically electrons, through a conductor. When there is a potential difference (voltage) applied across a conductor, the free electrons will move in response to this voltage, creating a flow of electric current.


Positive ions and electrons can flow in a a solution but only electrons can flow in wires. What causes the electrons to move?

In wires, the movement of electrons is driven by an electric field created by a voltage source. This electric field exerts a force on the electrons, causing them to move. In contrast, in a solution, positive ions and electrons can move because of the flow of electric current through the solution.


What causes the electrons to move in the electromagnetic induction animation?

In the electromagnetic induction animation, the movement of electrons is caused by a changing magnetic field passing through a conductor. This changing magnetic field induces a voltage in the conductor, which in turn creates an electric current that causes the electrons to move.


What does voltage cause?

Voltage causes the flow of electric current in a circuit. It is the driving force that pushes electrons through a conductor, allowing electrical devices to operate. The higher the voltage, the more current will flow through the circuit.


The particles that move through a material to form an electic current are called?

Electrons


What causes heating in wire?

Heating in wire is caused by the flow of current through the wire. The resistance in the wire causes energy to be converted into heat as the electrons move. This heating effect is known as Joule heating.


Why do wires heat up?

Wires heat up when current flows through them due to resistance in the material. As electrons move through the wire, they collide with atoms, which causes them to vibrate and generate heat. This is known as Joule heating.


What unit measure the force that makes electron move in a electric current?

The force that causes electrons to move in an electric current is measured in volts, which is the unit of electrical potential difference. The flow of electrons is driven by this voltage, creating the current in the circuit.


What are the tiny particles that move through wires when a current flows?

The tiny particles that move through wires when a current flows are called electrons. These negatively charged particles carry the energy and information needed for electrical devices to function.


What makes car batteries work?

The reaction of the acid and lead causes electrons to move creating a DC 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.


What force pushes electrical current through wires and conductors?

Voltage is the force that pushes electrical current through wires and conductors. It creates an electrical pressure that drives the flow of electrons from areas of higher voltage to areas of lower voltage. This difference in voltage is what causes the electrical current to move through the circuit.
