A galvanometer having a coil of resistance 60 
shows full scale deflection when a current of 1.0 amp passes through it. It can be converted into an ammeter to read currents upto 5.0 amp by
A
putting in series a resistance of 15 
B
putting in series a resistance of 240 
C
putting in parallel a resistance of 15 
D
putting in parallel a resistance of 240 
Text Solution
Verified by ExpertsThe correct answer is:
C
where 
is the galvanometer resistance and 
is the shunt used with theammeter.
Where 
is the shunt used to read a 5 A current when the galvanometer can stand by 1 A.
in parallel.
