Lesson: Properties of Electric ChargePhysics
In this lesson, we will learn how to convert between the SI unit of charge, the coulomb (C), and the number of electrons that this corresponds to.
Sample Question Videos
To start a car engine, the car’s battery moves electrons through the starter motor. How many coulombs of charge are moved?
Static electric charges are commonly measured in microcoulombs (µC) and in nanocoulombs (nC).
How many electrons are required to produce a charge of nC?
How many electrons must be removed from an initially neutral object for the object to have a net charge of µC?
If electrons move through a pocket calculator during a full day’s operation, how many coulombs of charge move through it?
