CONSIDER THE DIAGRAM POSTED LATER. THE WIRES IN RED ARE PERFECTLY NON-CONDUCTING.


THE DATA NEEDED IS


          WORK OF BATTERY/ CHARGE     =     E


          INITIAL LENGTH OF THE WIRE    =      L


          AREA OF THE WIRE                       =      R


         YOUNG' MODULUS                        =       Y


                   MASS     IS           M         AND g IS KNOWN       .


NEGLECT ANY OTHER EFFECT.


                FIND CURRENT AS A FUNCTION OF TIME ONCE THE WIRE ATTAINS THE EQUILIBRIUM POSITION
WALK NOT AS IF YOU RULE THE WORLD...
BUT AS IF YOU DON'T CARE WHO RULES IT....

MAN WOULD DO NOTHING IF HE WAITED UNTIL HE COULD DO IT SO WELL THAT NO OTHER BEING CAN FIND FAULT WITH IT..................NEWMAN

WELL WE HAVE A NORMAL CIRCUIT THE GREY SHADED ONE IS
THE RESISTANCE AND IT IS CONNECTED BY A NON CONDUCTING ROPES TO LIGHT MASS M . THE DETAIL OF ROPE IS GIVEN ABOVE . THE TOP OF THE RESISTANCE IS CONNECTED AGAIN BY A NON CONDUCTING WIRE TO A CEILING . JUST CALCULATE I AS A FUNCTION OF TIME . THE CLOCK STARTS WHEN EQUILIBRIUM IS REACHED AND ASSUME CURRENT TO CHANGING INSTANTANEOUSLY
