What is electric current and how do positive and negative charges flow?
Understand the Problem
The excerpt discusses the concepts of electric charges in motion, explaining the nature of electric currents and the flow of both positive and negative charges. It introduces basic laws related to electric current, focusing on charge flow and time intervals.
Answer
Electric current flows from positive to negative. Electrons flow opposite, from negative to positive.
Electric current is the flow of electric charge, typically electrons. In conventional terms, current flows from positive to negative, while electrons flow from negative to positive.
Answer for screen readers
Electric current is the flow of electric charge, typically electrons. In conventional terms, current flows from positive to negative, while electrons flow from negative to positive.
More Information
Electric current is often visualized as the flow of positive charges due to historical conventions, though electrons (negative charges) actually move.
Tips
A common mistake is to assume electrons flow in the same direction as the current. Remember that they flow in opposite directions.
