A dc voltage with ripple is given by $$v\left( t \right)\,\,\,\, = \,\,\,\,\left[ {100 + 10\sin \left( {\omega t} \right) - 5\sin \left( {3\omega t} \right)} \right]$$ volts. Measurements of this voltage $$v\left( t \right),$$ made by moving-coil and moving iron voltmeters, show readings of $${V_1}$$ and $${V_2}$$ respectively. The value of $${V_2} - {V_1},$$ in volts, is _______.

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

Two ammeters $$X$$ and $$Y$$ have resistances of $$1.2$$ $$\Omega $$ and $$1.5$$ $$\Omega $$ respectively and they give full-scale deflection with $$150$$ $$mA$$ and $$250$$ $$mA$$ respectively. The ranges have been extended by connecting shunts so as to give full scale deflection with $$15$$ $$A.$$ The ammeters along with shunts are connected in parallel and then placed in a circuit in which the total current flowing is $$15A.$$ The current in amperes indicated in ammeter $$X$$ is __________.
