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).
