Current is would be equivalent to how much water I can get out of the pipe in a second.
Voltage is how much pressure that water is coming out at.

The two are linked but aren't the same thing.

Say I was thirsty, I can drink exactly how much I want from the end of a pipe.
I can cope with large amounts easily, it'll be like drinking out of a river but I can't cope with high pressures. That would be like drinking out of the end of a firehose.
