    10. How can galvanometer behaves as ammeter or voltmeter only just by adding resistance.Exactly how it gives the idea that it is showing current or voltage only just by making Ig current to pass thr galvanometer...???

    11. Are the shunt res. Variable for a single ammeter or galvanometer according to change in current.???
    8 years ago by Shah Darshan Jagdishbhai
    Ans 1 ->
    no as by changing current only potential drop changes....

    15. Correction to earlier question posted by SHIVASIS MOHANTY. In circuits consisting of electrical measuring instruments(like ammeter,voltmeter,potentiometer etc.) is the arrangement of resistors or capacitors affected i.e. suppose we take 4 resistors which are initially in parallel connection.Now if we connect a voltmeter to the 2nd resistor, will the 4 resistors still remain in parallel?

    21. Dear sir..suppose that if we remove the external 0.3 resistance...we can find out the balancing length for emf 1.5..if we do like that the balancing length comes out to be 187.5 cm which is not possible..can u explain sir???
    9 years ago by Abinay gangireddygari
    Ans 1 ->
    for no point on the wire the difflection will be zero in the galvanometer

    22. isn''t wire is of lenghth 1m?
    10 years ago by RAKSHIT MAINI
    Ans 1 ->
    In case of meter bridge wire length is 1m and in a normal lab potentiometer it is of 10m and can be of any length in a potentiometer....If length increases its sensitivity increases...
