The term 'kind of electricity' can be summarized by two crossword solutions: STATIC (6 letters) and accurrent (9 letters). STATIC electricity is a form of electrical charge that builds up on the surface of objects due to contact with other objects. It is caused by the transfer of electrons from one object to another, and can be seen in everyday phenomena such as when a balloon is rubbed against a person's hair and it sticks to them. Accurrent electricity is a type of electricity that flows through a conductor, such as a wire. It is generated by a power source, such as a battery, and is used to power electrical devices.
