3 x 100W = 300 W
4 x 75 W = 300 W
3 x 60 W = 180 W
4 x 25 W = 100 W
Total = 880 W
Power = E x I
I = Power / E = 880 / 120 = 71/3Amp
Assuming:
-- All bulbs are in parallel across the 120V
-- Every bulb is dissipating exactly its rated power
-- Power factor on the line is 1.0

Amps used by 32 watt fluorescent light bulbs?
If it is a 120volt light, then it is watts / volts. 32 watts / 120 = .2667 amps. <<>> fluorescent lights usually have a power factor around 0.6 so a 32 watt bulb would take around 32/(120 x 0.6) amps or 0.44 amps.
How many 200 watt light bulbs can be safely installed on a 30 amp curcuit?
If the wireing is done properly you can install as many as you want until the fuse blows. A 30 amp circuit means that up to 30 amps is safe and after that it becomes unsafe and the fuse blows. You can calculate the number of 200 W bulbs that will draw 30 amps if you know the voltage. Most 30 amp circuits are connected to 220 volts. The maximum power you can draw from this circuit, before the fuse blows, is current x volts or 30 x 220 = 6600 watts. So you should be able to connect at least 32 ,200 W bulbs to this circuit and possibly 33 bulbs which would put you right at the maximum. If your voltage is only 110 volts then the max power you can draw is 30 x 110 = 3300 watts and the max number of bulbs is 3300/200 = 16.5 which of course means only 16 bulbs.
How much can a 15W circuit breaker handle?
Answer for the US: Breakers are rated in amps, not watts. However, a 15A breaker can handle 15 amps, or about 1800 watts (using 120V), or 3600 watts (using 240V). However, this is only rated for noncontinuous loads (those not lasting for more than three hours). For continuous loads (loads lasting three hours or more), one must derate the circuit breaker by 80%. So for continuous loads, that same breaker should only have 1440 watts (using 120V), or 2880 watts (using 240V) on it.
How many amps do light bulbs draw?
Depend on watt and voltage use of light bulbs. You can use this ohm's law formular to calculate the current draw on light bulbs. I (current in amp) = P (watt)/ E (voltage) If 25W light bulb use in 115V AC (resident home) then current draw will be: 25/115 = 0.22A or 22 miliamperes. Hope this help.
How many light bulbs does it take to make a computer screen?
no there is not thousands of light bulbs on a computer screen. Instead there is a projector built in the computer projecting whatever for example google and then it appears on your screen. It is very clever i think personally
How many amps does 230 watts equal is you are using 120V ac circuit?
1.9 amps
How many amps is 9.8Kw?
To calculate the number of amps, you need to know the voltage of the circuit. Using the formula Amps = Watts / Volts, if the voltage is 120V, then 9.8kW at 120V would be approximately 81.67 amps.
How many amps would a 150 watt bulb draw in a 120v circuit?
1 amp
In your house wired for 110-V how many 60 watt light bulbs can you run at the same time without blowing a safety fuse?
Can't answer that w/o knowing the Ampere rating of the fuse. A standard house circuit being 15 amps you would load the circuit up to 14.7 amps with 27 light bulbs.
How many amps is 9000 watts?
To calculate the amps for a given amount of watts, you need to know the voltage of the circuit. If we assume a typical household voltage of 120V, then the calculation would be 9000 watts / 120V = 75 amps.
How many watts in a 115 volt refrigerator?
How many Amps is the fridge pulling? Multiply the Amps by the 120V circuit you're plugging into and you'll get your Watts.
How many 100 watt bulbs can a 110 volt circuit handle?
To answer this question, you need to know how many amps the circuit that is connected to the light bulb can handle. For home applications with a 15 amp circuit and no other loads connected you get: Power = Current * voltage, Substituting the known information yields: power = 15 amps * 110 volts, which is 1650 watts of total capacity. You have 100 watt bulbs, so: 1650/100 = 16.5 bulbs If your circuit is other than 15 amps, or if there is additional loads on the circuit, you must adjust the current or total capacity accordingly
Can you use a light timer that is rated at 15A and 115V with a circuit that is rated at 20A and 120V?
Yes, you can use a 15A, 115V light timer with a circuit that is rated at 20A, 120V. The light timer will only draw the current it needs, which is less than the maximum capacity of the circuit. Just ensure that the total load on the circuit does not exceed its rated capacity.
What is difference between 2000W and 1500W and how to find out how much powerelectricity each consumes?
To find the power will depend on the voltage the item uses. Assuming a 120 volt circuit divide the wattage by the voltage, this gives the amps used. 2000w / 120v = 16.67 amps. 1500w/ 120v = 12.5 amps used.
How many watts do you need for 26 amps?
To calculate the watts needed for 26 amps, you would multiply the amperage by the voltage. For example, if the voltage is 120V, the calculation would be 26 amps x 120V = 3120 watts.
How many 60 watt bulbs can a 15 amp handle?
A 15 amp circuit can handle approximately 8-10 60 watt bulbs. Each 60 watt bulb draws 0.5 amps of current, so you divide the circuit's amp rating (15 amps) by the current draw per bulb (0.5 amps) to get the approximate number of bulbs it can handle.
What is the max wattage for a 120V outlet?
The maximum wattage for a 120V outlet is typically around 1800 watts. This is because the standard amperage for a 120V outlet is 15 amps, and power (watts) is calculated by multiplying voltage by amperage.
