When charging an object with static electricity, the charge is typically in which range?

• A. Picoelectro coulombs
• B. Microcoulombs and nanocoulombs
• C. Coulombs
• D. Milliamps

Answer: (B)

Static charging stores only a small amount of charge on objects. The amounts involved in everyday static electricity are measured in microcoulombs (1e-6 C) to nanocoulombs (1e-9 C). These ranges reflect the number of electrons transferred that’s large enough to be noticeable but far smaller than a full coulomb, which would imply a huge amount of charge and a much stronger effect. A milliamp, on the other hand, is a unit of current (how fast charge moves), not the total charge stored, so it isn’t the right measure for how much charge is accumulated. So, the typical range for static charges on everyday objects is microcoulombs to nanocoulombs.
