Section 9.2 Charge

Electric charge is a fundamental property of an object. Objects that are "charged" can display interesting behaviors when interacting with electric fields that we will explore in this chapter.

Definition 9.2.1. Charge.

Charge is a physical property, measured in coulombs (C), that governs how an object interacts with electric fields.

Exercises Activities

1.

An atom always has the same number of protons as electrons. What is the total charge on such an atom?

2.

Suppose you have an object with a net charge of exactly 1.0 C. How many more protons than electrons are in this object? Based on this, do you think a net charge of 1.0 C is typical for an everyday object, or is it much larger or smaller than you would expect for an everyday object?
