Just multiply.

The formula you are looking for is W = I x E. Watts = Amps x Volts.
Divide Watts by Volts ; this gives you Amps.
Ohm's law states that you could calculate the current (Amp), resistance (Ohm), or voltage (Volt) as long as you know the other two. Watts is not part of this law. Therefore, your question does not give enough information.
To find watts in physics, you can use the formula: Watts Volts x Amps. This formula calculates power, which is measured in watts, by multiplying the voltage (in volts) by the current (in amps) flowing through a circuit.
Amps (amperes) measure current flow in a circuit, showing how much electricity is flowing. Watts measure power, representing the rate at which energy is consumed or produced. In simple terms, amps indicate the amount of electricity flowing, while watts indicate how much work or energy is being used.
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.
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.
The formula you are looking for is I = W/E. Amps = Watts/Volts.
To calculate the amperage, we can use the formula: Amps = Watts / Volts. In this case, it would be 70 watts / 13.8 volts ≈ 5.07 amps. So, with 70 watts and a voltage of 13.8 volts DC, the amperage would be approximately 5.07 amps.
power equals current times voltage 50w=(I)110v so 50w\110v = I .454 amps
To convert amps to watts, you need to know the voltage of the circuit. The formula to calculate watts is: Watts = Amps x Volts. Multiply the current in amps by the voltage in volts to get the power in watts.
To calculate the amps, you can use the formula: Amps = Watts / Volts. So, for 2000 watts and 110 volts, 2000 watts / 110 volts equals approximately 18.18 amps.
To calculate the amperage, use the formula: Amperes = Watts / Volts. For this situation, it would be 4000 watts / 115 volts ≈ 34.78 amps.
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
To calculate the current in amps, you can use the formula: Amps = Watts / Volts. For 499 kW at 208 volts, first convert kilowatts to watts: 499 kW = 499,000 watts. Then, divide by the voltage: 499,000 watts / 208 volts = approximately 2395.19 amps.
800 000 Watts / 600 Volts = 1333.3333333 Amps
The formula you are looking for is I = W/E. Amps = Watts/Volts.
To calculate the watts from amps, you need to know the voltage of the circuit. The formula to calculate watts is: Watts = Amps x Volts. So, without knowing the voltage in the circuit, it is not possible to accurately determine the wattage from just knowing the amperage.
