Electric charge is a fundamental property of matter. It is a scalar quantity that determines the interaction of objects with an electromagnetic field. Electric charge is measured in coulombs (C) and can be positive or negative. Like charges repel each other, while opposite charges attract. The concept of electric charge is important in many areas of physics and engineering, including electromagnetism, electronics, and electrochemistry. It plays a critical role in understanding the behavior of electric circuits, the movement of electrons in conductors, and the behavior of ions in solution.

The formula for determining the electric charge is defined as:

\(Q\) \(=\) \(I\) \(\cdot\) \(t\)

\(I\): The electric current

\(Q\): the electric charge

\(t\): the duration

The SI unit of electric charge is: \(coulomb\text{ }(C)\)
