About
1.6.4.2 Moving-coil meters
Critical damping is an important feature of moving-coil meters which
are used to measure current and voltage. When the reading changes, it is
of little use if the pointer oscillates for a while or takes too long to
settle down to the new reading. The new reading must be taken quickly in
case it changes again.
again the model can be used to understand the effects of increasing levels of damping.
1.6.4.2.1 No Damping
the picture shows no damping case b = 0
1.6.4.2.2 Light Damping
the picture shows light damping case b = 0.1
1.6.4.2.3 Critical Damping
the picture shows critically damping case b = 2.0Thus, a pointer is critically damped to allow it to move to the correct position immediately whenever a current flows through it or a voltage is applied across it.
1.6.4.2.4 Heavy Damping
the picture shows heavy damping case b = 5.0
1.6.4.2.5 Model:
