5. The heat caused by "electrical friction".
6. The process of diverting unwanted electrical charge directly into the earth.
9. The simplest form of electricity.
12. A narrow strip of metal housed in a protective case that burns out when current suddenly increases.
13. The flow of charge from one place to another.
15. Term that describes a circuit in which current flows through a completed path.
16. The SI unit of resistance.
18. An electrical device designed to hinder current flow in a circuit.
21. Electric current that flows first in one direction and then the other.
22. A material that allows current to flow through it with no hindrance.
24. Materials through which electric current does not flow easily.

1. This type of circuit has loads arranged in separate branches so that current is divided among them.
2. The law stating that opposite charges attract and like charges repel.
3. The term that refers to the amount an object hinders electron flow.
4. The type of charge an electron has.
7. The work per unit charge done to move electric charges between differently charged parts of a conductor.
8. A simple device that uses the laws of electrostatics to detect small electric charges.
10. An automatic switch that opens when current overloads a circuit.
11. Electricity travels through fluids by the motion of charged particles called _______.
14. Law which relates current, voltage, and resistance in a circuit.
17. This occurs when current passes a load, increasing the current through a circuit.
19. Arrows that indicate how a positive test charge in an electric field would move.
20. The act of transferring electric charge between two objects through direct contact.
23. The SI unit of electric charge.
