A 220 volt circuit is fused for 30 amps. How many 60 watt incandescent soft whote light bulbs with tungsten filament burning at 3,0000 celsius can be used at the same time in the circuit without tripping the fuse?
Homework Equations
N/A
The Attempt at a Solution
(w/220)=30
220=30 amps(w)
220/30 amps=7.33 watts

In one of your other posts you listed P = IV. That would be really useful here.

220/30 amps=7.33 watts
The maximum number of 60W light bulbs that can be used in a 30A 220V circuit is 25 bulbs. This calculation is based on the wattage of the bulbs and the amperage and voltage of the circuit.
There is a limit on the number of 60W light bulbs in a 30A 220V circuit because the circuit can only handle a certain amount of wattage before it becomes overloaded. If the circuit is overloaded, it can cause overheating and potentially start a fire.
No, it is not recommended to use higher wattage light bulbs in a 30A 220V circuit. This can lead to overloading the circuit and causing potential safety hazards. It is important to always follow the recommended wattage for the circuit.
If you exceed the maximum number of 60W light bulbs in a 30A 220V circuit, the circuit can become overloaded and cause issues such as flickering lights, blown fuses, or potential fire hazards. It is important to always stay within the recommended wattage for the circuit.
No, the number of 60W light bulbs that can be used in a 30A 220V circuit is limited by the wattage and amperage of the circuit. To increase the number of bulbs, you would need to upgrade the circuit to handle a higher wattage or use lower wattage bulbs.
