10  End of unit questions







                10.3   The diagram shows a simple circuit in which a cell is connected to a buzzer
                      and an ammeter.







                                                                   A












                      a   Copy the diagram. Add a voltmeter to show how you would measure the
                          voltage of the cell.                                                               [1]
                      b   What is measured by the ammeter?                                                   [1]
                      c   The reading on the ammeter is 0.4 A. What unit does ‘A’ represent?                 [1]


                10.4   What type of circuit is described by each of the following statements?
                      Answer ‘series’ or ‘parallel’.
                      a   All components are connected end-to-end.                                           [1]
                      b   The current in the circuit divides so that some flows through one component
                          and the rest through another component.                                            [1]
                      c   Two lamps are connected side by side so that each lights brightly.                 [1]
                      d   The current has the same value everywhere in the circuit.                          [1]
