Answer 2

Answer:

The correct answer is true

Explanation:

Electric current is the rate of flow of charge. Current generally refers to the flow of charge.

A stream of charged particles, such as electrons or ions, travelling through an electrical conductor or a vacuum is known as an electric current. The net rate of electric charge flowing through a surface or into a control volume is how it is calculated. Charge carriers, which can be any of a number of particle kinds depending on the conductor, are the moving particles. Electrons flowing over a wire are frequently used as charge carriers in electric circuits. They can be electrons or holes in semiconductors. Ions are the charge carriers in an electrolyte, whereas ions and electrons are the charge carriers in plasma, an ionised gas.

The passage of electric charge across a surface at a rate measured in amperes, or amps, is the SI unit of electric current.
