The power of power chords
A power chord is a note played along with its fifth above to create a chord. It can be two or three notes. The power chord is a triad missing the third so it is niether major nor minor. That is part of what makes it so versatile. Many single note fingerings can easily be converted to power chords. They are commonly associated with rock guitar and they are quite easy to play.
Once you have the power chord mastered, you can move the chord shape anywhere along the fretboard and it will still be a proper chord. Because it is only two notes (sometimes three but that is more of a barre chord) it is easily harmonized. The reason for having only two notes, is that it eliminates some undesired harmonics that can clutter the sound of a distorted or overdriven guitar. They also help beginners achieve a better tone from their instrument.
To play a power chord, pick a note and place your first (index finger) on the fret. On the string below it, place your middle or ring finger two frets to the right of the original note. There should now be one fret in between the two you are fingering.

The above is a diagram of the power chord fingering. For this example we have used a power chord in G (3rd fret, top string). You are now free to move about the fretboard using that same shape. Practice sliding your fingers without loosing the position.
Here is a video example we found on YouTube. It explains power chords and teaches you to play IronMan by Black Sabbath on guitar. Iron Man is a great example of how to use power chords on the guitar.
