A 32-watt fluorescent bulb, when used for 1 hour, will consume 0.032 kWh (32 watts ÷ 1000). The energy consumption can be calculated by multiplying the wattage by the number of hours used.
A 60 watt bulb used for 1 hour consumes 0.06 kWh (60 watts * 1 hour / 1000).
A 200W light bulb will use 0.2 kWh (kilowatt-hour) of electricity per hour of operation. If the bulb is on for 5 hours, it would consume 1 kWh.
To calculate the kilowatt hours (kWh) used by a 30 watt light bulb in 8 hours, we first convert the power to kilowatts: 30 watts = 0.03 kilowatts. Then, multiply this by the time in hours: 0.03 kW * 8 hours = 0.24 kWh. So, 0.24 kWh are used to light a 30 watt light bulb in 8 hours.
A 33 watt fluorescent tube consumes 33 watt-hours of electricity per hour. It means it uses 0.033 kilowatt-hours (kWh) of electricity in one hour.
I kW = 1000 W 100 / 1000 = 0.1 So a 100 W bulb uses 0.1 kW For one hour that's 0.1 kWh
