Step 1: Calculate the energy consumed by the bulb in one day. The power of the bulb is P = 200 W. The time it is lighted for is t = 1 day = 24 hours. The energy consumed is given by the formula E = P × t. E = 200 W × 24 h E = 4800 Wh Step 2: Convert the energy from Watt-hours (Wh) to kilowatt-hours (kWh). Since 1 kWh = 1000 Wh, we divide the energy in Wh by 1000. E = 4800 Wh1000 Wh/kWh E = 4.8 kWh Step 3: Calculate the total cost. The cost of electricity is N 40 per kWh. The total cost is the energy consumed (in kWh) multiplied by the rate per kWh. Cost = E × Rate Cost = 4.8 kWh × N 40/kWh Cost = N 192.00 The correct option is D. The final answer is N 192.00.
