Final answer:
The total number of units consumed in a 30-day month at 480 kWh is 16 kWh per day. This is equivalent to an average power consumption of about 666.67 watts or 0.67 kW. The monthly bill calculation depends on the cost per unit charged by the electricity provider.
Step-by-step explanation:
To calculate the total number of units consumed in a month and the corresponding monthly bill for a domestic connection, we'll use the information provided. For a 30-day month, if a household used 480 kWh of electricity, we can determine the daily electricity consumption by dividing 480 kWh by 30 days.
The daily consumption is 16 kWh per day. Since the average American household uses approximately 30 kWh per day, this household is using less than the average. To express this daily usage in terms of power, we consider that a consumption of 16 kWh over a period of 24 hours is equivalent to an average power consumption of about 666.67 watts (or 0.67 kW) since power is energy divided by time.
For the monthly bill calculation, you would need to multiply the total number of units consumed by the cost per unit charged by your electricity provider. As such details are not provided, we cannot calculate the actual bill. However, it is always recommended to contact the electricity provider for accurate billing information or consider switching to a different electricity plan if cost-savings or efficiency is a concern.
Additionally, to put this into context, the author's utility bills indicated a use of 3,152 kWh per year for a household of two, which results in a daily average per person that can be calculated and compared to the national average. The energy unit on electric bills is the kilowatt-hour (kWh), which makes these estimations straightforward.
