What is an electric current?
Understand the Problem
The question asks for a definition of electric current. This involves understanding the flow of electric charge, typically electrons, through a conductive material and its measurement in amperes.
Answer
Electric current is the flow of electric charge through a conductor.
An electric current is the flow of electric charge through a conductor. It is measured as the rate at which charge flows past a point in a circuit, typically in amperes.
Answer for screen readers
An electric current is the flow of electric charge through a conductor. It is measured as the rate at which charge flows past a point in a circuit, typically in amperes.
More Information
Electric current is analogous to the flow of water through a pipe. The ampere (A) is the SI unit of electric current, representing one coulomb of charge per second.
Tips
A common mistake is to confuse electric current with voltage or electric power. Current is the flow of charge, voltage is the electric potential difference, and power is the rate at which energy is transferred.
