How many amps does a 1000 watt 120v ballast use?
Max amps would be 1000 divided by 120.
How many amps would a 150 watt bulb draw in a 120v circuit?
1 amp
How many amps does 65 watt light bulb draw?
A 65 Watt incandescent light bulb should draw 65W/120V = 541.67mA
How many amps does a 50 gallon water heater with 2-4500 watt elements draw?
30
What is the number of AMPS for a 240V 2400 watt water heater?
Watts = Amps x Volts for a resistive load like a water heater.

How many amps will a 400 watt heater cartrige draw at 240 volts?
The formula you are looking for is I = W/E.
How much current does a 75 watt light bulb draw from a 120v wall outlet?
It's 75/120 and the answer is in amps.
Why would a high watt lamp draw more current than a low watt lamp?
Power is measured in Watts, power (Watts) = E (volts) x I (current - amps) current is determined by the internal resistance (R) of the lightbulb, the lower the resistance the more current will flow. 120v x 0.5a = 60W 120V x 0.83a = 100W the 100W lightbulb will draw more current We also have Ohm's law: E(volts) = I (amps) x R (ohms) Household voltage stays the same at 120v we have for a 100w lamp: 120v = I x R R = 120v/0.83 amps R = 144.6 ohms for a 60w lamp: 120v = I x R R = 120v/0.5 amps R = 240 ohms The higher watt lamp has lower resistance.
How many watts does it take to run a heat mat?
I don't know what exactly you mean by a "heat mat", but your question is kind of backwards. You don't run an electrical device *with* watts. You run them to *produce* watts (watts of light, watts of heat, watts of sound, etc). I believe the thing you are really asking is how many amps are required to run your device. As an example, consider a "1500 Watt heater" that is made to be plugged into a typical wall outlet in your home. The voltage in the wall is 120V, and the heater will produce 1500 watts of heat when plugged into that 120V. To calculate the amps, you divide the watts by the voltage. 1500W / 120V = 12.5A
How do you work out how many amps a forty watt bulb uses?
figure out how many amps are in a watt and x by 40
What would be the amperage draw of a single phase 1200 watt heater if voltage is 120?
10 Amps. Amps=Watts/Volts
How many amps can a 9000 watt generator produce?
If your generator is rated at 1000 watts continuous......and you are using 120V.....available amps are 1000/120 =8.3 .
