Question

What happens when electric current passes through a copper wire?

Answer 1

When an electric current passes through a copper wire, it causes the free electrons in the copper atoms to move in one direction. These moving electrons create a flow of electrical energy, which can be used to power electrical devices, such as lightbulbs, motors, and electronic devices. The flow of electrons also generates a magnetic field around the wire, which can be used in applications such as electromagnets. Overall, the passage of electric current through a copper wire allows for the transmission of electrical energy and the operation of various electrical devices.
