Note:
Torches Power the Block Above
Of course, there is an exception to this rule. The redstone torch powers
the block above it rather than the block it is attached to.
Now, here's the important part. All sources except the redstone block also strongly power
the space they occupy, not just the anchor. (Redstone blocks are anchored on themselves,
so they only provide strong power to the space they occupy.) This provides a choice of two

occupied by the power source item.
Figure 9.5
shows how this works.
1.
This wire is powered by the space occupied by the lever
2.
This wire gets its power from the block the lever is anchored to
3.
Redstone torches power the block above, so this wire gets its power from the
cobblestone block above the torch
4.
The torch also powers the space it occupies, firing up this redstone wire
FIGURE 9.5
Sources provide strong power to two blocks each.
Keeping the two-block rule in mind gives you many more options for linking components
and running circuits. In other words, more power to you!
