$A$ stray magnetic field does $\underline{\text{NOT}}$ affect the deflection of a moving coil galvanometer because

  • A
    magnetic field inside the galvanometer is zero.
  • B
    magnetic field is equal to the earth's magnetic field.
  • C
    magnetic field inside the galvanometer is very strong.
  • D
    magnetic field inside the galvanometer is very weak.

$A$ galvanometer with its coil resistance $25\,\Omega$ requires a current of $1\,mA$ for its full-scale deflection. In order to construct an ammeter to read up to a current of $2\,A$,the approximate value of the shunt resistance should be:

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

$A$ galvanometer of resistance $G$ is converted into a voltmeter of range $0-1\, V$ by connecting a resistance $R_{1}$ in series with it. The additional resistance that should be connected in series with $R_{1}$ to increase the range of the voltmeter to $0-2\, V$ will be

$A$ shunt of resistance $1\ \Omega$ is connected across a galvanometer of $120\ \Omega$ resistance. $A$ current of $5.5\ A$ flows through the circuit,and the galvanometer shows full-scale deflection. What is the current that would cause full-scale deflection in the galvanometer in the absence of the shunt (in $A$)?
