Beyond the Answer
To calculate the energy dissipated by a 90 W lamp in 5 hours, we can use the formula: Energy (in watt-hours) = Power (in watts) × Time (in hours). So, Energy = 90 W × 5 hours = 450 watt-hours or 0.45 kilowatt-hours. This means the lamp will use enough energy to power a small appliance for a short time!
Understanding energy consumption is not just important for saving on electricity bills but is also a step towards being more environmentally friendly. By knowing how much energy devices use, you can make informed decisions about which appliances to upgrade to energy-efficient models, helping reduce overall carbon emissions.
