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.
To convert watts to amps, you can use the formula: Amps = Watts / Volts. For example, if you're using a 120V circuit, 450 watts would be equal to 3.75 amps (450 watts / 120 volts = 3.75 amps).
The amperage in the circuit can be calculated using Ohm's Law: Amperage = Voltage / Resistance. Plugging in the values, we get Amperage = 110V / 7ohms = 15.71A. Therefore, the circuit would have approximately 15.71 amps of current flowing through it.
To calculate the number of amps, you need to know the voltage of the circuit. Using the formula Amps = Watts / Volts, if the voltage is 120V, then 9.8kW at 120V would be approximately 81.67 amps.
To find the number of amps in a circuit with 115 volts and a power rating in watts, you can use the formula: Amps = Watts / Volts. So, if you have a device that runs at 115 volts and consumes 575 watts, the amperage would be approximately 5 amps (575 watts / 115 volts = 5 amps).
