संकल्पना:

भार शक्ति = 150 watts

 UPS में उपयोग की गई बैटरी का रेटिंग = 12 Volts, 150 Ah

बैटरी द्वारा आपूर्ति की गई ऊर्जा = वोल्टेजx Ah

बैटरी द्वारा आपूर्ति की गई ऊर्जा = 12 × 150 = 1800 watt-hour

∴ एक बैटरी 1800 watt-hour की ऊर्जा की आपूर्ति कर सकती है।

बैकअप समय = (बैटरी द्वारा आपूर्ति की गई ऊर्जा)/(भार शक्ति)

बैकअप समय \(=\frac{1800}{150}=12~h\)
