 The wire behaves like a magnet

• ### What happens when an electric current flows through a wire?

• What happens when an electric current flows through a wire? If wire have high Resistance it will heat up. Wire will have a small magnetic field around it..If voltage is high corona will be formed around wire.

• ### What creates current in a circuit?

• This movement of electrons from one atom to another is what creates an electric current. A consistent flow of electrons within a circuit determines the current in a wire. See how to calculate potential energy to understand electrons and energy. What is Current? Electric current is defined as the flow of electrons in a circuit.

• ### What is electric current?

• Electric current is defined as the flow of electrons in a circuit. This current is derived from the continuous jumping of the negatively charged electrons from one atom to another. The standard unit of measurement of electric current is Ampere (A). Electric current exists in two forms, the direct current (DC) and alternating current (AC).
