|
| To measure the average EU/t transferred through a wire over time an [[EC-Meter]] can be used. If clicked once on a cable it will begin measurement.

| == EU/p ==
| | 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. |
| EU/p means '''Energy unit per packet''', and is the amount of energy contained in each EU packet. It is also known as voltage.
| |
| This is important because machines will explode and wires will melt if they are exposed to packets which are too large.
| |
|
| |
|
| EU/p is almost always fixed for a given wiring setup, as opposed to EU/t which may change as machines turn on and off, storage units fill up, or generators run out of fuel. [[Nuclear reactor]]s and some generators from addons can emit different packet sizes, but most devices always emit the same size packets. | | 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 ranges from 1 to 2048 EU, and can occasionally be higher. The sum of the EU value of all EU-Packets travelling through a cable or device in one tick is EU/t. | | == EU/p == |
| | |
| There is also packets/tick, or p/t, which can be involved in calculations but is not normally used. If all packets on a wire are the same size, then on that wire EU/t = EU/p * p/t.
| |
|
| |
|
| === Emitters ===
| | ''Note: the contents in this section isn't yet approved by an IC2 developer. They might be incorrect.'' |
| * Generators and storage devices emit one packet/tick. This means their EU/p output = their EU/t output.
| |
| * [[BatBox]]es emit 32 EU/p (and therefore 32 EU/t). [[MFE Unit]]s emit 128 EU/p. [[MFS Unit]]s emit 512 EU/p.
| |
| * Transformers behave somewhat like storage units. An LV tranformer will store up to 128 EU. An MV transformer will store 512 EU. An HV transformer will store 2048 EU. In addition, they are capable of outputting 4 packets/tick. This means a single MV transformer can output 512 EU/t and 128 EU/p when in step-down mode. It cannot output 2048 EU/t and 512 EU/p in step-up mode because it cannot store 2048 EU.
| |
|
| |
|
| === Cables ===
| | The "voltage" in IC2 E-net. |
| [[Cable]]s are limited by the size of EU-Packets that may travel through, NOT the number of packets, NOR the total EU/t contained by these packets. If an EU Packet too large for a cable to handle tries to pass through, the cable will be destroyed.
| |
|
| |
|
| For example, an unlimited amount of 32 EU-Packets can pass through a Copper cable per tick, but not a single 128 EU-Packet.
| | 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. |
|
| |
|
| Energy loss of a cable is applied to every EU-packet, not the total EU/t passing through. Ex. Using a gold cable, sending 4 32 EU-Packets in a cable (by using 4 [[batbox]]s) results in 4 times the energy loss of sending one 128 EU-Packet (by using a [[MFE Unit]]). See the [[Cable#Voltage Efficiency|Voltage Efficiency]] section for more information.

| Quote from Zjarek of the Industrial-Craft 2 Forums:
| |
| | |
| "In IC2 electricity is only a buzz word for small magical dwarfs carrying nanobatteries. From every energy source or storage there is one dwarf released every tick. Size of a dwarf is determined by amount of energy they are carrying. Cables are in reality just a tunnels where they run. If a cable or machine don't provide enough space for a dwarf it will get angry and blow up.
| |
| | |
| However many dwarfs are happy to run alongside each other and will in cooperation carry any amount of energy through a cable. Big dwarf will still prefer to blow up, then to split, but he can split into smaller dwarfs in transformer. Every smaller dwarf which is produced by transformer can go to the same output tunnel.
| |
| | |
| These useful little creatures are also sometimes nicknamed packets."
