Why is higher voltage lower amps

Kelly Marie Angel

This question mite be unanswerable  but here goes we all know that if you gave say 1 Kw at 110 volts it's about 10 amps but 1 Kw at 240 volts is about 4 amps what I was wondering is why?  Amps is the flow of current so how can you have less flow doing the same work?  That's my real question. As always not to heavy on the maths please cheers all Kelly

  • Because power = volts x amps. If you double the voltage, you must halve the amps otherwise the power would double also.
