A periodic waveform observed across a load is represented by
$$$V\left( t \right) = \left\{ {\matrix{
{1 + \sin \,\omega t} & {0 \le \omega t < 6\pi } \cr
{ - 1 + \sin \,\omega t} & {6\pi \le \omega t < 12\pi } \cr
} } \right.$$$
$$6\pi \le \omega t < 12\,\pi $$
The measured value, using moving iron voltmeter connected across the load, is

The dc current flowing in a circuit is measured by two ammeters, one PMMC and another electrodynamometer type, connected in series. The PMMC meter contains 100 turns in the coil, the flux density in the air gap is 0.2 Wb/m2
, and the area of the coil is 80 mm2. The electrodynamometer ammeter has a change in mutual inductance with respect to deflection of 0.5 mH/deg. The spring constants of both the meters are equal. The value of current, it which the deflection of the two meters are same, is ___________.
