The number of watts in an amp depends on the voltage of the electrical circuit. The relationship between watts (W), amps (A), and volts (V) is given by the formula:
Watts=Amps×Volts\text{Watts}=\text{Amps}\times \text{Volts}Watts=Amps×Volts
This means that to find watts from amps, you multiply the current (amps) by the voltage (volts). For example:
- At 120 volts, 1 amp equals 120 watts.
- At 240 volts, 1 amp equals 240 watts.
Here are some examples for common voltages:
Amps (A)| Voltage (V)| Watts (W)
---|---|---
1| 5| 5
1| 12| 12
1| 24| 24
1| 36| 36
1| 48| 48
1| 110| 110
1| 120| 120
1| 220| 220
1| 230| 230
1| 240| 240
So, the number of watts per amp varies directly with the voltage of the system
. In summary, to find how many watts are in an amp, you must know the voltage, then multiply amps by volts to get watts. Without knowing the voltage, you cannot determine watts from amps alone.
