5 Multiple Choice Questions
- 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 rate at which electrical energy is converted to another form of energy; this is expressed in watts (W) or kilowatts (kW).
- The difference in electric potential energy between two different points; measured in volts (V).
- 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.
- A closed path through which electrons flow.
5 True/False Questions
ohm's law → States that potential difference=current X resistance, or V (volts)=I (amperes) X R (ohms).
resistance → The force exerted by a machine to overcome resistance to gravity or friction
electric field → A device containing two suspended metal leaves in a jar that move apart when charged; used to detect the presence of electric charges.
static electricity → 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.
dry cell → A power of source that acts as an electron pump and generates electric current by a chemical reaction
