4 volts and how many amps? Watts = amps x volts. It depends on the amount of current (in Amps) flowing at 4 Volts...
See Ohms Law: Watts = Volts x Amps
If you have 2 Amps flowing at 4 Volts you are dissipating/consuming 8 Watts.
If you have 10 Amps flowing at 4 Volts you are dissipating/consuming 40 Watts.

How many watts is 18.5 volts?
Watts is the product of amps x volts. To give an answer the amperage needs to be given.
4 ohms equals how many watts?
Ohms does not equal watts. You need to know what voltage is across the resistor to determine how many watts it is drawing or how many watts the resistor should be rated for.Power is the voltage across the resistor SQUARED divided by the resistance. If this 4 ohm resistor has 12 volts across it then the watts power is (12 x 12) / 4 = 36 watts.1 Watt equals 1 Volt times 1 Amp.
How many amps are in 40 watts?
That depends on circuit voltage. 1 watt is equal to 1 volt times 1 amp.
How many amp is 450 watts 24 volts?
That gives you 18.5 amps.
How do you find OHM?
Ohms can be found by using these formulas. Ohms = Volts/Amps, Ohms = (Volts (squared))/Watts, Ohms = Watts/(Amps (squared)).
How many volts are there in 1367 watts?
volts times amps = watts
How many watts are in 30 volts?
There is no direct relationship between watts and volts. Watts = volts x current in amps.
How many watts is equal to 4.3 amps at 230 volts?
In normal simple circuits WATTS = VOLTS x AMPS So if you use a 12V car battery 4 amps is 48 Watts American 110V mains 4 amps = 440 Watts English 240V mains 4 amps = 960 Watts
How many watts in 115 volts?
Watts and Volts are two distinct types of measurement.
How many amps with 70 watts 13.8 Volts dc?
Watts = Volts * Amps Therefore: 70 Watts / 13.8 Volts = 5.07 Amps
How many amperes in a watt and how many watts in a volt?
Amps, volts and watts are interrelated, but you need to do a little math. Amps * Volts = Watts
How many volts are 200 watts?
Zero. Watts is the product of Amps x Volts. As you can see an amperage value is needed. Voltage = Watts/Amps. Volts = 200/? 20 volts
How many volts does it take to make 1 horsepower?
Volts don't make power. Watts do. Watts = (volts) x (amps) 1 horsepower = 746 watts
How many volts do you need to power 2 watts?
watts = volts x amps, example-2 watts=2 volts x 1 amp, example- 2 watts=120 volts x .60 amp.
At 12 volts how many watts is 30 amps?
Watts is volts times amps, so 12 x 30 = 360 watts
How many watts of electric on a 13 amp fuse 240 volts?
You need the formula: Amps * Volts = Watts But you get to do the math.
How many volts it takes to cause a current of 1.95 amps to exist in a 200 watt lamp?
The formula to calculate the relationship between amps, volts and watts is Volts X Amps = Watts or Volts = Watts / Amps or Amps = Watts / Volts therefore; 200 Watts divided by 1.95 Amps is 102.5641 Volts.
