I want to be able to play electric.
An acoustic guitar generally has thicker strings which are further from the fretboard (called action) and doesn’t need an amplifier. An electric guitar generally has thinner strings and has a lower action (strings are closer to the fretboard) and requires an amplifier to hear very well and get decent sustain out of the notes you play. If you start on an acoustic, you need to press harder against the strings to get them to sound your note correctly. When you first begin playing, your fingers will be weaker and less coordinated than after you’ve played for a while and, possibly more importantly, you won’t have developed callouses on your fingertips. That means that your finger muscles will experience fatigue and your fingertips will be sore and probably blister faster playing an acoustic. That will probably lead to slightly less practice time. The biggest problem with starting to play an instrument is that it’s hard (at first) and you get discouraged. You will find the acoustic more difficult to play initially because of these reasons.
The upside to starting on an acoustic is that if you are determined to play and keep up your practicing without being discouraged, you will find that when you do switch to an electric, you may be amazed at your speed and dexterity on an electric since it is much easier to play. Plus, not having to invest in an amp right away is great for your bank account.
