Question
Outline the necessary steps to convert a galvanometer of resistance RG into an ammeter of a given range ?
Solution
Conversion of a galvanometer to ammeter
• A shunt (low resistance) is connected in parallel with the galvanometer.
`S = ((I_g)/(I -I_g))G`
Where,
I → Total current in circuit
G → Resistance of the galvanometer
S →Resistance of the shunt
Ig → Current through galvanometer
