EU - '''Energy Unit''' is the measure of energy production, consumption, transmission and storage.
{{Experimental}}


These units are not similar to IRL electricity, basically this is "virtual" items, that can stack unlimited amount of times and needs storage items like [[RE Battery]] or [[cable|transportation\distribution]] network to be used.
EU - '''Energy Unit''' is the measure of energy used by IC2. It is most similar to the SI derived unit [[wikipedia:Joule|Joule]]. EUs are 'produced' by [[generator]]s, transmitted along [[cable]]s, stored by mobile units like an [[RE Battery]] or by stationary units like a [[batbox]], and 'consumed' by various IC2 machines.
EU stored in items or devices wont decay over time.


All Industrial Craft 2 machines involved in production or consumption of EU.
EU is not related to Redstone signal, but some machines can be affected by redstone signals, and a [[Detector Cable]] produces a redstone signal if there is any EU passing through it.


EU is not related to Redstone current, but, multiple machines can be affected by redstone currents, also Detector Cable can produce redstone current if any EU passing it.
Some machines allow a lever to be mounted directly on it.
Some machines allow lever to be mounted directly on it's block.


Raw EU value used to measure capacity of energy storage items or blocks.
Raw EU values are directly used to measure the capacity of energy storage items or blocks.


== EU/t ==
== EU/t ==


EU/t means '''Energy unit per tick'''.
The "amperage" in IC2 E-net.
If SSP or SMP server able to handle all ingame calculations, clockrate ~20 ticks per second.
If server not able to handle game, clockrate will drop significantly and you will notice ingame time slowdown.
If clockrate is 10, ingame second will last as long as 2 IRL seconds.


EU/t used to measure EU consumption and production, '''EU/t''' can be measured with an [[EC-Meter]] by clicking on any cable two times with some delay.
EU/t means '''Energy unit per tick'''. It measure how fast EU is being produced or consumed. It is a derived unit of energy over time, similar to the SI derived unit [[wikipedia:Watt|Watt]].


== EU-Packet / Voltage ==
To measure the average EU/t transferred through a wire over time an [[EU-Reader]] can be used. Right-click with it on a cable it will begin the measurement.


'''EU-Packets''' are the transmission containers of [[EU]]s. They represent voltage in Industrial Craft 2.
EU/t transfer can also be observed by the rate of change in EU capacity displayed by storage devices and malike the [[batbox]].
This value have nothing with IRL voltage.


EU-Packets come in different sizes ranging from 1 EU to 2048 EU, unlike IC1 you may not change EU output of storage devices.
Minecraft normally operates at 20 ticks per second, unless you are experiencing server [http://minecraft.gamepedia.com/Tick lag]. Therefore, under no lag conditions, the rate of EU/sec is 20x EU/t.


There is no way to measure what size of packets travels through a [[cable]] or machine but they can be read from EU emitting blocks.
Machines and cables will explode if they are exposed to too much EU/t. This differs from the old system, where there was a separate "voltage."
In the current system, voltage and EU/t are the same thing.


Emitters such as generators, storage units, and transformers, can emit EU-Packets.
== EU/p ==


=== Emitters ===
''Note: the contents in this section isn't yet approved by an IC2 developer. They might be incorrect.''
* Generators emit packets as big as their output is.
* Storage Units always emit packets the size of their "out" value.
* Transformers behave like Storage Units. They additionally able to upgrade 4 packets into one of higher tier or downgrade single packet into 4 of lower tier, behaivior controlled by redstone currents.


=== Cables ===
The "voltage" in IC2 E-net.
[[Cable]]s can carry unlimited amounts of EU/t but only EU-Packets that are the same or below of their maximum Voltage. You can send unlimited amounts of 32 EU-Packets through a Copper cable but not a single 128 EU-Packet. The clue is that energy loss of a cable isn't connected to the total amount of EU/t but to every single packet. So sending 100 32 EU-Packets results in 100 times the energy loss of the cable where sending one 2048 EU-Packet only result in one time the energy loss of the cable. More on that in [[Cable#Voltage Efficiency|Voltage Efficiency]].


=== Packet Sizes ===
EU/p means '''Energy unit per packet'''. In IC2, EU is ''always'' being carried in cables in "packets", which is just a bunch of EU traveling together in the same time. There is a packet size, which determines how many EU travels together at a same time. The maximum packet size determines the voltage. EU storage blocks only send out 32EU/p, 128 EU/p, 512 EU/p and 2048 EU/p depending on its tier, while generators can send out varying packet sizes.

Experimental-Only Content: This information has been updated to the V2.X version of IC².
The most recent version of IC² is V2.8.<html>.

EU - Energy Unit is the measure of energy used by IC2. It is most similar to the SI derived unit Joule. EUs are 'produced' by generators, transmitted along cables, stored by mobile units like an RE Battery or by stationary units like a batbox, and 'consumed' by various IC2 machines.

EU is not related to Redstone signal, but some machines can be affected by redstone signals, and a Detector Cable produces a redstone signal if there is any EU passing through it.

Some machines allow a lever to be mounted directly on it.

Raw EU values are directly used to measure the capacity of energy storage items or blocks.

EU/t[edit]

The "amperage" in IC2 E-net.

EU/t means Energy unit per tick. It measure how fast EU is being produced or consumed. It is a derived unit of energy over time, similar to the SI derived unit Watt.

To measure the average EU/t transferred through a wire over time an EU-Reader can be used. Right-click with it on a cable it will begin the measurement.

EU/t transfer can also be observed by the rate of change in EU capacity displayed by storage devices and malike the batbox.

Minecraft normally operates at 20 ticks per second, unless you are experiencing server lag. Therefore, under no lag conditions, the rate of EU/sec is 20x EU/t.

Machines and cables will explode if they are exposed to too much EU/t. This differs from the old system, where there was a separate "voltage." In the current system, voltage and EU/t are the same thing.

EU/p[edit]

Note: the contents in this section isn't yet approved by an IC2 developer. They might be incorrect.

The "voltage" in IC2 E-net.

EU/p means Energy unit per packet. In IC2, EU is always being carried in cables in "packets", which is just a bunch of EU traveling together in the same time. There is a packet size, which determines how many EU travels together at a same time. The maximum packet size determines the voltage. EU storage blocks only send out 32EU/p, 128 EU/p, 512 EU/p and 2048 EU/p depending on its tier, while generators can send out varying packet sizes.


Types of Voltage[edit]

The amount of EU/p is relative to the voltage level. In IC2, voltage is categorized into 5 levels:

Types of EU Levels EU/P Size
Low Voltage 32 EU/p or lower
Medium Voltage 33-512 EU/p
High Voltage 513-2048 EU/p
Extreme Voltage 2049-8192 EU/p
Insane Voltage >8192 EU
