How to Calculate Total Electrical Load in a House
What is the total load when all lamps are operating?
The four rooms of a house contain lamps with the following wattages:
- The living room has 4-150 watt lamps
- The dining room has 5-75 watt lamps
- The master bedroom has 2-75 watt lamps and 4-150 watt lamps
- The bathroom has 3-65 watt lamps
Final Answer:
The total electrical load when all lamps in the four rooms of the house are operating is 1920 watts.
Explanation: This problem involves the addition of wattages from various lamps in different rooms of a house to find the total electrical load in watts when all lamps are operating. This can be solved by calculating the wattage of lamps in each room and then combining them.
The Living room has 4 lamps of 150 watts each, totaling: 4 * 150 = 600 watts.
The Dining room has 5 lamps of 75 watts each, totaling: 5 * 75 = 375 watts.
The Master bedroom has 2 lamps of 75 watts and 4 lamps of 150 watts, totaling: (2 * 75) + (4 * 150) = 150 + 600 = 750 watts.
The Bathroom has 3 lamps of 65 watts each, totaling: 3 * 65 = 195 watts.
Adding up all these totals, the overall load when all lamps are operating is: 600 watts + 375 watts + 750 watts + 195 watts = 1920 watts.
