Frequently Asked Questions
How do volts, watts, and amperes relate to each other?
Watts equals volts times amperes (P = U x I). Volts measure electrical pressure, amperes measure current flow, and watts measure power consumption. For household outlets in Germany: 230V x 16A = 3,680W maximum.
What fuse size do I need?
Divide the device wattage by the voltage (230V in Germany) to find the required amperes. A standard household circuit uses 16A fuses, suitable for up to 3,680 watts.
What is the Volt-Watt-Ampere Calculator?
The volt-watt-ampere calculator converts between electrical voltage, power and current and computes the missing quantity.
How does the Volt-Watt-Ampere Calculator work?
Enter two of the three quantities: voltage (volts), current (amps) or power (watts). The calculator determines the third using the formula P = U * I.
Key Data and Facts
Formula: watts = volts * amps. Household mains Germany: 230 volts. 16 A fuse: max. 3,680 watts. Three-phase power: 400 volts, typically 32 A.
