Vedclass · Answer

(A) dead-beat galvanometer is designed to bring the pointer to rest quickly without oscillations.When the coil of the galvanometer moves in the magnetic field,it induces eddy currents in the metallic frame (usually made of aluminum or copper) on which the coil is wound.According to Lenz's Law,these eddy currents oppose the motion of the coil,providing magnetic damping.This damping effect causes the pointer to come to a steady deflection rapidly,making the galvanometer 'dead-beat'.

The pointer of a dead-beat galvanometer gives a steady deflection because

State the principle of a moving coil galvanometer.

The sensitivity of a moving coil galvanometer is $s$. If a shunt of $\frac{1}{8}$ of the resistance of the galvanometer is connected to the moving coil galvanometer,what will its new sensitivity be?

$A$ 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?

Two galvanometers $A$ and $B$ require $3\,mA$ and $5\,mA$ respectively to produce the same deflection of $10$ divisions. Then:

The deflection in a moving coil galvanometer is reduced to half when it is shunted with a $X \ \Omega$ coil. The relation between $X$ and the resistance of the galvanometer $G$ is:
