A galvanometer having a coil resistance of $60Ω$ 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 :NEET 2009 (Mains)

Options:

Answer:

Solution:

$Ig S G = 1.0 A, G = 60 q, I = 5.0 A = \frac{I _{g}}{I - I _{g}} G = \frac{1.0}{5.0 - 1.0} = 60 = 15Ω in parallel$
