Is there any way to construct a resistor within a redstone circuit? I was thinking that there might be some properties of cobblestone versus glass, dirt versus obsidian, etc. but I haven't had the opportunity to check it out. Is there any data on this?

(I realize that there probably aren't resistors in Minecraft YET, but i'm really hoping i'm wrong)

What are you hoping to use the resistor to do? That might get more answers, especially as I'm betting most folks aren't electrical engineers. – Raven Dreamer Nov 9 '10 at 23:20
Which is to say -- though we might know what a resistor does, we haven't a clue why they're so darn useful. – Raven Dreamer Nov 9 '10 at 23:26
They aren't particularly useful for binary circuits like redstone emulates. For analog circuits, however, they are important to limit current, among other things. – StrixVaria Nov 9 '10 at 23:31
I'm wildly fantasizing about constructing a working synth, to be completely meta and make video game music in a video game. resistors are the first step out of many. – Nick H Nov 10 '10 at 0:23

No; redstone can be used to emulate logic gates, not electrical components. There is no analog to any electrical component, nor any use for them.

If what you want is to slow down/delay the signal (which is not what resistors do), you can use a redstone repeater.

Thank you very much. – Nick H Nov 10 '10 at 0:23

You can use a Redstone Comparator to produce a desired signal strength. When set to subtract mode, the signal being produced out the front will equal the back input minus the side input.

Therefore if you have a repeater directly behind the comparator (15 signal strength), and a lever with two pieces of dust going into the side (14 signal strength) the comparator will output 1 signal strength.

If the comparator has two side inputs, it will simply use the most powerful one.
