    Q36 C if the motor connection is broken why is there still a potential drop of 24V across the motor ? Does current still flow through the motor and the circuit if motor connection breaks ??

      As explained there, no current would flow.

      The voltmeter actually gives the potential difference - that is a difference in potential. Since the value read is 24V, it means that that -ve connection has broken. Thus, current flows from the positive terminal of the supply, to the +ve connection, through the motor, to point Y and now through the voltmeter (instead of the lower wire in the cable).

      The motor is actually OK but it is not working because one of the wires in the cable has broken.
