Electric Current
Electric current is the rate at which electric charge flows through a conductor.
Practice This ConceptMain explanation
Teacher explanation
In simple terms, current tells us how fast charge is moving in a circuit. If more charge passes a point in less time, the current is larger. Its SI unit is ampere, and it is a basic quantity used in every circuit calculation.
Example
If 10 coulombs of charge pass through a wire in 2 seconds, the current is 5 ampere.
Simple analogy
Current means charge flow per second.
Common confusion
Many students write the total charge as current instead of dividing charge by time.
Exam tip
Always write the unit as ampere and use I = Q/t in numerical questions.
