When measured with an infrared thermometer it read 169.9 degrees F.
A 120 volt table lamp with a 75 watt bulb will pull 0.625 amps. With a 100 watt bulb it will pull 0.833 amps. And with a modern fluorescent 13 watt bulb it will pull 0.108 amps.
"Nick Holonyak, 75, invented the LED (light emitting diode) in the 1960s."
The amount of light produced and the amount of power consumed. A watt is a unit of power and electrical power is determined using the formula: P = I2*R , Where P is power, I is amps and R is resistance. But using Ohm's law ( V = I * R) the following can be obtained: P = V2/R , Where V is voltage. In US house holds the standard voltage is ~120V, changing the resistance of the filament of the light bulb will change the amount of power consumed and therefore the amount of light produced. The higher the wattage the lower the resistance of the filament. Filaments are used in standard incandescent light bulbs and not in fluorescent tubes or LED fixtures.
Thomas Edison invented light because he made light so why not bulbs
Considering an incandescent bulb and using P=VxI P= Power Watts V= Volts I= Current (amperes) I=P/V I=75Watts/120Volts = 0.625 Amperes (A or Amps) Therefore the current through a 75watt bulb that is connected to a 120volt circuit is 0.625 amps.
It depends on the bulb
A 15-watt fluorescent should produce about as much light as a 75-watt incandescent.
In the sense of 'work' as force moving through a distance, a light bulb does none of that. But in the sense that mechanical work is equivalent to energy in other realms, the 75-watt light bulb consumes 75 joules of electrical energy every second, and radiates 75 joules per second of energy in the form of light and heat.
A 75 bulb will use more electricity.
25 watts?
It's 75/120 and the answer is in amps.
1 Joule = 1 Watt.sec, ie 1 Watt for 1 second. A 75 Watt bulb dissipates 75 Joules every second, so the answer is 10/75 of a second = 0.1333 seconds
Yes.
Usually the 60-watt limit is used to prevent the lampshade overheating, so a 75-watt bulb should not be used. But if more brightness is required, try a low-energy bulb because a 15-watt one gives the same light as a 75-watt incandescent (old-style) bulb. Or a 20-watt would be even brighter.
The fixture manufacturer goes on the side of safety. A 75 watt bulb puts out both more light and heat than a 60 watt bulb. It can make the fixture burn out sooner. For even more light, why don't you go with a florescent and get a 27 watt bulb that gives off the same amount of light as a 100 watt bulb? That will give off far less heat and be far better for your fixture?
This depends on many factors.
