Is there a certain way that resistors are supposed to be installed? Answered

If I were to run 3 LEDs with a resistor to each one.. Would it matter which side of the resistor is connected to the positive side?

Doesn't matter, they look nicer if they are all the same way.

Agreed.  If you can, install them so that all the colour bands face the same way.  It just looks more professional.

Its ALSO neat that you line them up the way they are placed on the wiring diagram. That way you don't crick your neck trying to read them upside down....

Resistors are mainly used to resist the flow of current. They do not act as diodes, so, it doesn't matter how you connect it or to which side of it is the positive terminal connected.

Any way is a good way.

It wouldn't matter if it was on the positive side or the negative side, but you would have to put them in series.

It's supposed to be 1 LED (+ side) & 1 resistor (1 side only) soldered together . You also have to check the LED tolorence (how many watts or volts it can handle before it blows up), the resistor resisance (how many watts or volts it can hold back), & how much electricity the source (battery, plug, wire, cable, etc.) gives.

 it doesn't matter but i would put all the gold bands on the same side to make it easier to read

keydogstony is right. Resistors are not polarity sensitive - and if you have a circuit that is don't worry.

The Right way
(which is no particular way by the way!)

Either way is fine.  The current is the same whether it flows through the resistor then the LED or the LED then the resistor as they are in series.

Nope. Resistors are not polarity sensitive.
