Final answer:
The load inequality sums up to the total electrical system capacity of 18,000 watts, which matches the combined wattage of the listed appliances, indicating no additional capacity available. If you want to calculate available electricity, subtract the wattage of running appliances from the total capacity. In an example, running a 5000 W air conditioner and a 500 W microwave leaves 12500 W for other appliances.
Step-by-step explanation:
The given load inequality is:
- 1100 W
- 600 W
- 1150 W
- 1800 W
- 5000 W
- 500 W
- 8(60 W)
- 70 W
- 240 W
These wattages could correspond to everyday household appliances. First, let's calculate the total electricity used up by these appliances:
Total = 1100 + 600 + 1150 + 1800 + 5000 + 500 + 8(60) + 70 + 240 = 18000 W
Which simplifies to:
Total = 18000 W
It seems that the equation given is already at the total capacity for the electrical system, which is 18,000 watts. Thus, the sum of the individual wattages of these appliances is equal to the total capacity, and no additional appliances can be added without overtaxing the system.
If these appliances were running things like air conditioners, heaters, a microwave, etc., and you wanted to know how much electricity is available after running certain appliances, you would subtract the total wattage of the running appliances from the capacity.
For example, if only the 5000 W (air conditioner) and 500 W (microwave) appliances were running:
Available = 18000 W - (5000 W + 500 W) = 12500 W available to use for other appliances like an electric kettle or a television without overloading the circuit.
