Alrite peeps, this is my first question not to mention thread so go easy on me if there's a thread for these types of questin

I've recently purchased my first electric guitar (fender strat) and i'm starting to learn power chords. Are all strings meant to be strummed when being played or just the 3 being held?

thanks in advance to whoever answers!

Yeah, power chords don't use all the strings.
I know exactly what I think I'm doing.

Try to hit just the fretted strings...however, as a beginner, you should use your index finger to dampen the other strings, just lay it flat across them, in case you're a messy player like me and just wildly beat at all the strings.
