Study Notes

Definition of Electric Current

Electric current is the flow of electric charge through a conductor.
It represents the movement of electrons in a circuit.

Units of Measurement

The standard unit for measuring electric current is the Ampere (A).
One Ampere is equivalent to one Coulomb of charge passing through a given point in one second.

Symbol for Current

The symbol used to represent electric current is "I".

Relation Between Charge, Current, and Time

The equation that relates charge (Q), current (I), and time (t) is:
- Q = I × t
This equation indicates that the total charge is the product of the current and the time duration during which the current flows.

Interaction of Oppositely Charged Conductors

When two oppositely charged conductors are connected, a current flows between them.
This movement is caused by the attraction of opposite charges, resulting in a discharge of the stored energy.
