In this case Watts = Volts x Amps. If we assume 120 volts there is 1 Amp per bulb. Theoretically that would be 20 bulbs. However, for continuous operation you should be at only 80% of the load current or 16 Amps. So the answer is either 20 or 16 depending on if this is a math problem or a quiz for an electrician.

How many bulb can conekt through 15 amp breaker?
Well it depends on the wattage of the bulbs. At 120 V, with power = current x voltage, you have power = (15 A) x (120 V) = 1800 watts. So if you have 100 W bulbs, then the maximum possible before the breaker should trip is 18 bulbs. It is not a good idea to operate near the limits of the circuit design, though.
How many 75 watt bulbs can be placed on track lighting with 20 amp breaker?
Theoretically a 75 watt bulb at 120 volts draws .625 amps. You would add the individual currents to determine maximum amperage. That would be 32 bulbs. However, you would then be right on the edge and breaker would likely trip often. You should de-rate to 80% of the breaker rating or 16 amps in this case. That would be 25 bulbs. You should also check to see if there is a maximum amperage or wattage rating on the track. Twenty Five bulbs will create quite a heat source.
What happens to the current measured as more bulbs added?
It is unclear what type of circuit you are referring to, so I'll give both answers.parallel, current increases until too many bulbs have been added, then circuit breaker pops and current drops to zero.series, current decreases and all bulbs dim.
Bedroom breaker keeps tripping out what can I do to correct this?
You need to identify specifically what is causing the breaker to trip. It could just be that you have to many devices or appliances on the circuit; or it could be a problem with the wiring, switches or outlets. Some steps to take. 1.) Unplug everything from the circuit. If it doesn't trip anymore you had too much plugged in. Identify what can be switched to another circuit. 2.) What device or appliance causes the problem? It is most likely something like a heater or something with a motor; or perhaps too many higher wattage light bulbs. 3.) If the breaker always trips when it rains, you may have a water moisture problem? 4.) If the breaker trips when nothing is connected it may be the breaker or a short in an outlet or switch.
Why would the breaker kick off when adding a run of lights with a switch at the end of the lights?
I really need more detailed information to answer your question. How many lights were added and what wattage bulbs are being used? For a 15-amp breaker, the maximum wattage it would handle would be around 1650 watts. This would be about 16 100-watt bulbs. Does your breaker trip immediately when you turn the light switch on? If you have an ohmmeter you can check the tripped breaker. Put one lead on the black "hot" wire coming from the breaker. Remember, the breaker must be off. Then put the other lead on the ground bar. If the ohm reading is very low, close to 2 ohms, then you have a direct short to ground somewhere in your wiring.
How many 115 volt outlets could you run from a 20 amp breaker?
If you never plug anything into them, there is no limit. If the total current drawn from all outlets exceeds 20 amps, the breaker will trip.
How many 100 watt lights per breaker?
I would use no more 14 100watt bulbs on a 15 amp circuit or 19 bulbs on a 20 amp circuit. You can calculate this by taking 80% of circuit amperage I.E 12 amps or 16 amps and then multiply by circuit voltage(120) to get 1440 watts and 1920 watts. Then take these values divided by bulb wattage(100 watts) to get 14.4 bulbs and 19.2 bulbs. Then round down for partial bulbs to get 14 bulbs and 19 bulbs.
How do you change bulbs in a 1997 Blazer?
There are many bulbs on a vehicle, need to know which bulbs you want to change.
How many lights can you put on one 15 amp breaker?
15 amps at 120 volts will handle a maximum of 1800 watts. But you should never load the circuit to more than 80% which will be 1440 watts. Divide the wattage of each light into 1440 to see how many you can install. Example: Installing 75 watt fixtures you could install no more than 19. This is assuming there are only lights on the circuit and no outlets.
How many watts do big bulbs use?
The usual criteria is that the larger the envelope size of the lamp the larger the wattage of the lamp. The terminology of "big bulbs" suggests that the lamp could be in the range of 400 watts.
How many bulbs are there in mysore palace?
1 Lakh Incandescent bulbs.
Can you install a tandem breaker?
Tandem breakers, often called split breakers or double breakers, provide two separate circuits in the space of a regular sized breaker opening. Every circuit breaker panel has a limited number of circuit openings available. The problem is that when the openings are all used up and you still need to add another circuit, what do you do? You could change the electrical panel or double up circuits on a breaker, but this could place too much load on a particular circuit. So what then? The answer that many have found is a tandem breaker. This type breaker is the same size as any other breaker, but it has its difference. This breaker sports two smaller breakers built into one regular sized breaker. Each has its own breaker switch and the breaker snaps in just like a regular breaker. With this simple innovation, you can add a circuit and protect the circuit on its own dedicated line.
