GATE Electrical 2014 Set 3 | Question: 47
A periodic waveform observed across a load is represented by $V(t)=\begin{cases} 1+\sin\omega t & 0\leq \omega t< 6\pi \\ -1+ \sin\omega t & 6\pi \leq \omega t< 12\pi \end{cases}$ The measured value, using moving iron voltmeter connected across the load, is $\sqrt{\dfrac{3}{2}} \\$ $\sqrt{\dfrac{2}{3}} \\$ $\dfrac{3}{2} \\$ $\dfrac{2}{3}$
A periodic waveform observed across a load is represented by$V(t)=\begin{cases} 1+\sin\omega t & 0\leq \omega t< 6\pi \\ -1+ \sin\omega t & 6\pi \leq \omega t< 12\pi \end...
