$A$ galvanometer acting as a voltmeter should have . . . . . . .

Explain the equation of a shunt.

Explain the construction and principle of a moving coil galvanometer.

$A$ 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 $A$)?

Which of the following does not depend upon the magnetic effect of current?

$A$ galvanometer has resistance '$G$' and range '$V_g$'. How much resistance is required to read voltage up to '$V$' volt?
