If an ammeter is connected in parallel to a circuit,it is likely to be damaged due to excess

$A$ galvanometer with a resistance of $8 \, \Omega$ is connected to a shunt of $2 \, \Omega$. If the total current is $1 \, A$,how much current in $A$ passes through the shunt?

$A$ galvanometer of resistance $50 \Omega$ gives a full-scale deflection for a current of $5 \times 10^{-4} \text{ A}$. The resistance that should be connected in series with the galvanometer to read $3 \text{ V}$ is: (in $Omega$)

Explain: "Increasing the current sensitivity may not necessarily increase the voltage sensitivity".

$A$ $72 \; \Omega$ galvanometer is shunted by a resistance of $8 \; \Omega$. The percentage of the total current which passes through the galvanometer is $.....$

Derive the expression for the shunt resistance required to increase the current-measuring capacity of a galvanometer by a factor of $n$.
