The simplest way to understandthe relationship between voltage and amperage is to think of it in terms of water flow. Voltage is pressure, amperage is volume. More pressure(voltage) = more volume(amperage) for the same size pipe(wire). Thus, less pressure at the same volume means you need a bigger pipe. The longer the pipe, the higher the head loss, the lower the flow.
