Study Notes

Measuring Charge

Charge (Q) on ions is measured by the amount of excess or deficit electrons they possess.
The unit of charge is the Coulomb (C).

Charging Objects

When an object is negatively charged, it gains one or more excess electrons, resulting in a net negative charge.

Electric Charge Equation

The equation Q = It represents the relationship between electric charge (Q), current (I), and time (t).
Q is the total charge, I is the current flowing, and t is the time over which the current flows.

Definition of Coulomb

One Coulomb (C) is defined as the quantity of electric charge that flows through a cross-sectional area of a wire in one second, when the current is one Ampere (A).
