Cable amperage?

What does “amperage” mean when I try to use a cable (wire)? Is it the number of machines that can be connected like the channel of Ae2? Or is it the relationship between the EU and voltage, like Ohm’s law?

Energy in GT6 is transported in packets. The Voltage is the size of packet while the Amperage is the number of packets per tick. You may not transfer more packets per tick than the Amperage rating, and each packet may not exceed the Voltage rating.
While there isn’t something like Ohm’s Law, AFAIK the Cable Loss is computed per packet, so multiple packets (higher Amperage) means more loss and transforming to higher Voltage means less loss.

So if the voltage is 256 and the ampere is 2, it sends 512 EU/t?

It sends 2 packets, each of which is 256 EU/t. Added together it drives a machine at 512 EU/t. But the Cable Ratings should not be confused with the actual value, which is determined by the machine emitting power.

Now I understand thank you!
