How many volts are needed to power a 60 watt light bulb?
MaxLite 60 Watt Incandescent Equivalent, 13 Watt, 120 Volt A Style CFL Bulb.
Then you can use ohms law to get an answer: For example, if you have 120 volts and an amperage of 10 amps, multiply 120 x 10 = 1200 watts.
- Using Ohms law, you would multiply amperage times volts to get watts. For instance a 12 volt circuit drawing 2 amps would consume 24 watts of power (12*2=24). A 60 watt light bulb powered by 120 volts in a house would draw .5 amp of current (60/120= .5).
- Watts equals voltage times current, so any two numbers that multiplied together to give you 1500 will work. It does not matter which one you call voltage or current it's the same so: 100 volts at 15amps =1500 watts OR 10 volts at 150 amps equals 1500 watts, OR 1500 volts at 1 amp = 1500 wattsYou get the idea!
- For example 12 watts/12 volts = 1 amp.
Converting Amps to Watts.
The conversion of Amps to Watts at fixed voltage is governed by the equation Watts = Amps x Volts.
For example 1 amp * 110 volts = 110 watts.
Sockets are often marked with the voltage rating of the socket. That is the maximum voltage it can withstand without breaking down and arcing. They are designed to 250V to work with margin in 120V and 230/240 volt useage; they can be used with either of them.
- For dark kitchens and more opaque fixtures, try 100 watts. If you get a lot of natural light, try using a slightly dimmer 80 watt bulb. - Bathroom Sconces Keep bathroom sconces around 60-80 watts (But, this can be split. So two 40 watt bulbs in a pair of sconces or three 30 watt bulbs above the mirror for example).
- With newer light bulbs designed to use less energy, wattage is no longer a reliable way to gauge a light bulb's brightness. That takes lumens. A standard 60-watt incandescent bulb, for example, produces about 800 lumens of light. By comparison, a CFL bulb produces that same 800 lumens using less than 15 watts.
- Standard 100-watt bulbs produce about 1600 lumens. Watts - the amount of energy a light bulb uses. The lower the watts, the lower the electric bill. CFLs and LEDs have a lower wattage than incandescent bulbs, but emit the same light output.
