Definition
Electric charge is a physical quantity of matter which causes it to experience a force when near other electrically charged matter.
It comes in two types, called positive and negative, and they interact as follows:
- Two positively charged bodies repel each other.
- Two negatively charged bodies repel each other.
- Positively charged and negatively charged bodies are attracted to one another.
It is a scalar quantity which has been demonstrated to be quantized.
Dimension
Electric charge is frequently, at elementary levels at least, considered as one of the fundamental dimensions of physics.
In dimensional analysis it is assigned the symbol $Q$ or $\mathbf Q$.
