5 Multiple choice questions
- An area surrounding an electron that exerts a force on anything nearby with an electric charge; is strongest nearest the electron and weakens with a distance.
- A closed path through which electrons flow.
- An electrical circuit where the current flows through more than one path. If one path is interrupted, current will still flow through the other paths.
- The unit of electrical energy
- A material that does not allow heat or electrons to move through it easily.
5 True/False questions
electrical power → An area surrounding an electron that exerts a force on anything nearby with an electric charge; is strongest nearest the electron and weakens with a distance.
dry cell → A power of source that acts as an electron pump and generates electric current by a chemical reaction
resistance → The force exerted by a machine to overcome resistance to gravity or friction
ohm's law → States that potential difference=current X resistance, or V (volts)=I (amperes) X R (ohms).
static electricity → An electrical circuit where the current has only one path. If the path is interrupted in any point, it stops current flow in the entire circuit.
