Lesson: Electric Current as Rate of Flow of ChargePhysics
In this lesson, we will learn how to express electric current in terms of the rate of net movement of electric charge past a point in a conducting circuit.
Sample Question Videos
How many electrons flow through a point in a wire in 3.00 s if there is a constant current of 4.00 A?
The quantity of charge through a conductor is modeled as . What is the current at time s?
The charge that flows through a point in a wire as a function of time is modeled as , where C and s.
What is the initial current through the wire at time s?
Find the magnitude of the current at the instant T.
At what value of will the current be reduced to exactly ?
