-[* black] Insert wisdom here.
+[* black] These, my friend, are resistors. Resistors are used in circuitry to control the amount of current flowing through a given circuit. Much like water flowing through a pipe, the narrower the resistor is, the less current that flows through it.
+[* black] The difference between the two resistors shown is their amounts of resistance. But how can you tell? See those little colored rings, that's how you know.
+[* black] The first ring to locate when reading a resistor is the one on one of the swollen ends. These are called tolerance bands. No resistor is exactly the value it indicates, so [|tolerance bands] tell you within what percent the reading is. In our case, the tolerance band is gold, indication a 5% tolerance.
