we can say also on this way.

you need to push ( or pull ) a car. How many men you need to do it ?

More men, will mean less effort made from each man

But you'll need ALLWAYS to push ( or pull ) 4K lbs.

well the totall effort made to push the car is the volts.

the AMOUNT OF MEN needed is the AMPERES. More "amperes", less effort by each man... less stress on the "force generator"

sounds good ? I tried to make it more basic as posible
