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 C 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?
