The guitar power chord is one of the very basic but important chords for any guitarist to know. You can use this versatile chord in any key and genre, but it’s mostly used in metal, heavy metal, grunge, punk and rock music.
The power chords are made up of the root note and the fifth, but can also be played with a third note, in which case you would use the index, ring, and pinky finger, or use your ring finger to barre the two strings, this is if you use the 3 note power chord.
For the 2 note chord you would only use your index and ring finger. There are other variations but this is the most used ones, and would get you a long way.
