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

  • If you had a tank of water 110 metres high and the flow down the pipe is a certain amount (say 10 Ebee units).

    Another tank of water at 240 metres high and the flow is 4 and a bit Ebee units, then they are both working the same.

    V (Electrical Pressure) x Amps (current flow) = Watts (power).

    If you lift a weight of 10 pounds upwards one foot, that is ten foot pounds of work.

    If you lift a weight of 1 pound up ten feet then that is still ten foot pounds.

    Hope that helps.
