How Many Amps Does a 100 Watt Light Bulb Draw?


A 100 watt light bulbs draws 0.833 amps from a 120 volt supply. To calculate the correct reading, Voltage (V) is multiplied by Current (I). A watt represents a unit power (P). Example; Current (I)= Watts (P) / Voltage (V). 100 watts/120 volt supply= 0.833 amps

The formula you are looking for is I = W/E. Amps = Watts divided by Volts.
Power (Watts) = Current (Amps) * Voltage (Volts)
W = V * A. Watts = Volts X Amps.
