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.
