The deflection in a moving coil galvanometer falls from $50$ divisions to $10$ divisions, when a shunt of $12 \mathrm{\Omega }$ is connected across it. The resistance of the galvanometer is

A galvanometer has a resistance of $3663 \mathrm{\Omega }$. A shunt $\mathrm{S}$ is connected across it such that $\left(\frac{1}{34}\right)$ of the total current passes through the galvanometer. Then the value of the shunt is

An ammeter gives full deflection when a current of $2 \mathrm{A}$ flows through it. The resistance of ammeter is $12 \mathrm{\Omega }$. If the same ammeter is to be used for measuring a maximum current of $5 \mathrm{A}$, then the ammeter must be connected with a resistance of

A milliammeter of resistance $5 \mathrm{\Omega }$ gives a full scale deflection for a current of $15 \mathrm{mA}$. If the milliammeter is to be used to measure current upto $1.5 \mathrm{A}$, then the resistance that must be attached to the milliammeter is

A galvanometer of resistance $25 \mathrm{\Omega }$ is shunted by $2.5 \mathrm{\Omega }$ resistance. The part (fraction) of the total current that flows through the galvanometer is given as

A galvanometer of resistance $36 \mathrm{\Omega }$ is shunted by a resistance of $4 \mathrm{\Omega }$. The percentage of the total current passing through the galvanometer is

In an ammeter, $10\%$ of the main current is passing through galvanometer, if the galvanometer is shunted with a $10 \mathrm{\Omega }$ resistance. What is the resistance of the galvanometer?

In order to pass $10\%$ of main current through a moving coil galvanometer of $99 \mathrm{\Omega }$, the resistance of the required shunt is

A galvanometer $(G=1000 \mathrm{\Omega })$ gives full scale deflection when a current $10 \mathrm{\mu A}$ flows through it. It is required to measure a current whose maximum value does not exceed $1 \mathrm{A}$. To do so we need to connect a resistance of
