In a series LCR circuit, the rms voltage is $100\ \mathrm{V}$, the rms current is $2\ \mathrm{A}$, and the power factor is $0.6$. The average power dissipated is: / श्रेणी LCR परिपथ में वर्ग-माध्य-मूल वोल्टता $100\ \mathrm{V}$, वर्ग-माध्य-मूल धारा $2\ \mathrm{A}$ और शक्ति गुणांक $0.6$ है। क्षयित औसत शक्ति है:
1.
$60\ \mathrm{W}$ / $60\ \mathrm{W}$
2.
$100\ \mathrm{W}$ / $100\ \mathrm{W}$
3.
$120\ \mathrm{W}$ / $120\ \mathrm{W}$
4.
$200\ \mathrm{W}$ / $200\ \mathrm{W}$
Correct Answer: $120\ \mathrm{W}$ / $120\ \mathrm{W}$
$P = V_{rms}I_{rms}\cos\phi = 100 \times 2 \times 0.6 = 120\ \mathrm{W}$. / $P = V_{rms}I_{rms}\cos\phi = 100 \times 2 \times 0.6 = 120\ \mathrm{W}$।
