EU stands for Energy Unit and is the unit of energy used by IndustrialCraft 2. It is similar to the SI unit of the Joule. EU can be created through various IC2 generators. EU can be stored in various blocks and items including BatBox, Energy Crystal, BatPack, and many more. EU can be transported through cables to power various IC2 machines.
EU/t means Energy Units per Tick. It is a derived unit that represents the energy transferred over time and is similar to the Watt. EU/t can be measured by an EU-Reader, giving the average EU/t flowing through a cable or block. EU will not flow if there is nothing to actively draw it.
An EU-Packet (EUP or EU/p) represents a discrete unit of energy. All machines and cables accept a maximum packet size and many devices (such as transformers and energy storage units) will only output energy in specific packet sizes. EU-Packets come in varying magnitudes from 1 EU to 1 million EU. The average value of all EU-Packets traveling through a cable per tick is the same as EU/t.
Different types of Cable will only be able to handle a certain size of packet, represented in the following table:
|Name||Packet Size||Emitted By||Cable|
|Micro Voltage||1-5 EU||Solar Panel , Water Mill , Wind Mill|
|Low Voltage||32 EU||BatBox, LV Transformer, Nuclear Reactor, Generator, Geothermal Generator, Advanced Solar Panel, Radioisotope Thermoelectric Generator|
|Medium Voltage||128 EU||CES Unit, MV Transformer, Nuclear Reactor, Hybrid Solar Panel|
|High Voltage||512 EU||MFE Unit, HV Transformer, Nuclear Reactor, Ultimate Hybrid Solar Panel|
|Extreme Voltage||2048 EU||MFS Unit, EV Transformer, Nuclear Reactor|
Note: Cables are rated for specific packet sizes, or EU/p, not EU/t. Thus a single cable may deliver power to or from multiple machines, even if all accept or produce the maximum packet size for that particular cable.
