  • 2000Va 1400 Watts 5.83 Amps
  • 2500Va 1750 Watts 7.29 Amps
  • 3 kVa 2.1 kWatts 8.75 Amps
  • 4 kVa 2.8 kWatts 11.67 Amps
  • 5 kVa 3.5 kWatts 14.58 Amps
  • 6 kVa 4.2 kWatts 17.50 Amps
  • 7 kVa 4.9 kWatts 20.42 Amps

    We remember the formula as WAV - Watts = Amps x Volts

    By dividing both sides of the formula by amps you get - Watts / Amps = Volts ... the amps / amps on the right hand side canceling each other out to leave volts.

    And by dividing both sides by volts you get - Watts / Volts = Amps ... the volts / volts on the right hand side canceling each other out to leave amps.

    Examples

    Q What is the biggest electric fire that can be run on a 13 amp fused plug in the UK?

    A Mains voltage in the UK is 240v so Watts = 13 x 240 = 3120 watts or just over 3kW

    Q A 60 watt car spotlight is showing a drain of 5.5 amps on the ammeter. What is the voltage?

    A 60 / 5.5 = 10.9 volts

    Q A food mixer with a 400 watt motor runs in the US on 120 volt supply. What fuse to fit?

    A 400 / 120 = 3.33 amps. A 5 amp fuse would be ok.
