amps equals watts divided by volts.
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.
You just have to divide the watts by the voltage to find the amps. For example 60 watts on a 120 v system would take ½ amp.
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.
calculation for Watts is = volts X amps P=IE P= Power(WATTS) I = Current(AMPS) and E = Voltage(VOLTS). So: I = P/E and E = P/I therefore: 1 watt = 1 ampere x 1 volt If you havea 240 volt lamp that is drawing .5 amp then it is using 120 Watts

The amps drawn by a 65 watt light bulb should be 65/120 or 0.54167. This fraction of an ampere may be restated as 541.67 milli-amps.
A 65 Watt incandescent light bulb should draw 65W/120V = 541.67mA
About 1/2 amp.
draw 0.104 amps
On this calculation I am assuming that the light bulb is using a 120 volt source. Watts = Amps x Volts. Amps = Watts/Volts, 40/120 = .33 amps. R = Volts/Amps, 120/.33 = 363.6 ohms resistance in the 40 watt light bulb.
It will take a current of 46 amps.
"Amps" is a steady thing. There's no such thing as "Amps per hour".The current through a 24-watt load is[ 24/the voltage across the load ] Amperes.
~9.1 Amps P [W]= E [V] x I [A]
To answer this question the voltage of the bulb is needed.
It depends on the voltage and whether the lamps are actually 40 watts or 40 watt equivalent. Watts / volts = amps
You need the volts times the amps to equal 100 Watts. On 12 v that is 8.33 amps, or on 200 v is it 0.5 amps.
