You will often need to know how much an aquaponics sump, timer, air pump or other device uses to plan for backup power such as solar, battery, generators etc. This formula shows you how:
Electrical Formula to Get Watts
- Amps = Watts/Volts
- For example 12 watts/12 volts = 1 amp
- Watts = Amps x Volts
- For example 1 amp * 110 volts = 110 watts
- Volts = Watts/Amps
- For example 100 watts/10 amps = 10 volts
