Question

Physics

An AC voltage is given by: E = E₀ sin \(\frac{2 \pi t}{T}\). Then, the mean value of voltage calculated over any time interval of T/2 seconds:

is \(\left(\frac{2 e_0}{\pi}\right)\) always

is always zero

is never zero

may be zero

AC वोल्टेज इस तरह दिया जाता है: E = E0 sin \(\frac{2 \pi t}{T}\)। फिर, T/2 सेकंड के किसी भी टाइम इंटरवल पर कैलकुलेट किए गए वोल्टेज की मीन वैल्यू:

\(\left(\frac{2 e_0}{\pi}\right)\)हमेशा

हमेशा ज़ीरो होता है

कभी ज़ीरो नहीं होता

ज़ीरो हो सकता है

View Answer & Solution

Correct Answer: D (may be zero) D (ज़ीरो हो सकता है)
