Question

deduce an expression for galvanometer to ammeter​

Answer 1

Answer:

If the current Ig in the coil produces a full-scale deflection , then the current I in the circuit corresponds to the full-scale deflection . Thus , with a shunt S of the above value , the galvanometer will be an ammeter of range 0 to I ampere (A) . S / G = 1 / 9
