how LT meggar works

Answer Posted / deepak

The moving system consists of two coils, the "control coil"
and the "deflecting coil"-rigidly mounted at an angle to one
another and connected, in parallel across a small generator,
with polarities such that the torques produced by them are
in opposition. The coils move in the air gap of a permanent
magnet. The control coil is in series with a fixed control
circuit; the deflecting coil is connected in series with a
fixed deflecting circuit resistance and the resistance under
test. If this last is infinitely high no current flows in
the deflecting coil and the control coil sets itself
perpendicular to the magnetic axis, the pointer indicating
"Infinity." A lower test resistance allows current to flow
in the deflecting coil and turns the movement clockwise. The
control torque produces a restoring torque which
progressively increases with the angular deflection, and the
equilibrium position of the movement is attained when the
two opposing torques balance.
