Static: Static electricity is the result of gathering of electric charges that occurs when two non-metallic objects rub against each other. Dynamic: Dynamic electricity is the flow of electric charges through a conductor. Static current is one which is constant with time.

Answer:
Static electricity: When there is no flow of electrons. It is a only result of imbalance between positive charges and negative charges . The electrons do not move and remain stationary.
- This phenomenon is generally found in insulators.
- When two insulators such as a plastic scale and a rubber balloon are rubbed against each other. Both insulators become electrically charged.
- While one will lose some electrons and other will gain some electrons. The substance that will lose electrons get positive charge and the substance will gain electrons get negative charge.
- These charges remain on the surface of the substance and are stationary.
- Examples: Static electricity is reason that balloon becoming able to stick on to a wall, scale can attract small pieces of paper etc.
Dynamic electricity: When the flow of electrons can be either in a single direction which is called direct current or it can be changing directions repeatedly termed as alternating current.
- When electrons can free from a substance and start to flow in a material, it forms dynamic electricity.
- If electrons will flow in a single direction, the current generated by them is known as direct current (DC). For example: the current generated in the battery of our car.
- If electrons will change their direction continuously or repetitively from positive to negative. The electricity produced is known as alternating current (AC). Such type of electricity that is supplied to our homes and necessary to run all our appliances.
