What would be the total energy consumption of a 100-watt bulb running for 5 hours?

Explanation:
To calculate the total energy consumption of a 100-watt bulb running for 5 hours, we can use the formula for energy consumption, which is power multiplied by time. In this case, the power of the bulb is 100 watts and the time is 5 hours. The calculation can be set up as follows: Energy (in watt-hours) = Power (in watts) × Time (in hours) By substituting the values into the formula: Energy = 100 watts × 5 hours = 500 watt-hours However, when discussing energy consumption in terms of watts, it's important to clarify that 1 watt-hour equals 1 watt consumed for 1 hour. Therefore, the total energy consumed can also be represented as 500 watt-hours, which is equivalent to 0.5 kilowatt-hours (kWh). The reason the total energy consumption is often expressed as 500 watt-hours rather than a simple watt measurement, such as 1000 watts, is that watt is a measure of power at a specific moment, while watt-hours is a measure of energy over time. Thus, the total energy consumption for the specified duration and power is accurate at 500 watt-hours, which aligns with the understanding that multiplying the consistent
