5 Multiple Choice Questions

  1. 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.
  2. The rate at which electrical energy is converted to another form of energy; this is expressed in watts (W) or kilowatts (kW).
  3. The difference in electric potential energy between two different points; measured in volts (V).
  4. 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.
  5. A closed path through which electrons flow.

5 True/False Questions

  1. ohm's lawStates that potential difference=current X resistance, or V (volts)=I (amperes) X R (ohms).

          

  2. resistanceThe force exerted by a machine to overcome resistance to gravity or friction

          

  3. electric fieldA device containing two suspended metal leaves in a jar that move apart when charged; used to detect the presence of electric charges.

          

  4. static electricityAn electrical circuit where the current flows through more than one path. If one path is interrupted, current will still flow through the other paths.
