Static and Dynamic Electricity

These are 2 types of electricity.

Static electricity refers to two charge objects.  One with an excess of electrons and one with a shortage.  A electric (force) field exists between the 2 objects.  The charge stored in the object is called static electricity.

If the 2 objects become too close or the charge build up become too great, the attractive force will caused electrons to jump across the space from one object to the other. This is called electrostatic discharge (ESD).  ESD is generally not useful as the charges are dissipated quickly in sparks or quick flow of electricity.

Dynamic electricity refers to the electricity that we know to power appliance.  This is a constant flow of electrons.  There must be voltage source that cause the electrons to flow from negative terminal to the positive terminal.  Current is measured as the number of electrons that pass through a certain point in a specific period of time.  One ampere of current equals to 1 Coulomb of charge per second.  One Coulomb of charge equals to 6.242 x 10^18 electrons.
