Step 1: Calculate the total time the lamp is used. The lamp is used for 6 hours daily for 30 days. Total time = Daily usage × Number of days Total time = 6 hours/day × 30 days = 180 hours Step 2: Calculate the total energy consumed in Watt-hours (Wh). The power of the lamp is 100 W. Energy consumed = Power × Total time Energy consumed = 100 W × 180 hours = 18000 Wh Step 3: Convert the energy consumed from Watt-hours (Wh) to kilowatt-hours (kWh). Since 1 kWh = 1000 Wh: Energy consumed in kWh = 18000 Wh1000 Wh/kWh Energy consumed in kWh = 18 kWh Comparing this result with the given options: [A] 18 kJ [B] 18 kWh [C] 1.8 J [D] इनमें से कोई नहीं (None of these) The calculated energy matches option [B]. The final answer is B. Send me the next one 📸
