Step 1: go to http://www.wolframalpha.com/ because we are lazy. Step 2: Enter "(d/dD) ((8 * 4^T - (D - 1)L) / (8 * 4^T + 2^T))^(1 / D) = 0, T=<Insert tier here>, L=<Insert Cable loss here>". It will solve the problem numerically for each separate case. So if you want to know the optimal length of Annealed Copper Cable between your MV Batteries, you enter T=2, L=1 and it will give you the optimal length of each segment (This includes the battery!). In the case of Annealed Copper Cable this turns out to be about 24.1, so 23 cables between each battery is optimal. For more information on other cables, see the table above.

Once you have crafted your first EBF and started MV tier. You will gain access to producing MV (Medium Voltage, 128v) which is great! However. You will need to transform this energy into LV power to use it with your existing LV machines since LV Machines will explode if they are given too high voltage.

The Transformer allows you to convert GT Energy between voltage tiers.

The big hollow circle is the Higher voltage side and is the front of the transformer, while the 5 smaller circles is the lower voltage sides.

By default the Transformer is taking 1 amp of higher voltage and transforms it into 4 amps of lower voltage. This is also called Step-Down mode. Ingame it will say “Machine Active” when toggling to this mode.

You can also hit the transformer with a Soft Mallet to switch between its two modes.

In Inverted mode, Step-Up mode (“Machine Inactive”), the Transformer will take 4 amps of lower Voltage and transform it into 1 amp of Higher voltage.

Keep in mind that in this mode the lower voltage sides become the Input, and the higher voltage side is therefore the Output.

You should never change mode on a transformer that has power. Always disconnect cables before switching mode on the Transformers.

=== Power Transformer ===

The Power Transformer works like an ordinary transformer with one exception. It will accept 4 amps of higher voltage and turn it into 16 amps of lower voltage in its default mode.

In inverted mode it will transform 16amps lower voltage to 4 amps of higher voltage.
