Are e strings on and electric guitar the same as on an acustic?

It all depends on what type of acoustic guitar it is, if its a classical then its nylon strung, steel strung acoustics can use the same strings as an electric. Some people prefer "bronze" strings for their acoustic.

As a side note, It is important to understand strings and acoustic/classical Guitars.

Classical or palor guitars are best suited using nylon strings since most do not have truss rods in the neck. Therefore keeps the string tension less and not an aid in warping the neck. DO NOT put steel strings on a Classical guitar! Nylon strings also create a warmer more inviting sound for the style of music played.

A classical guitar has a slotted headstock not solid and tuning keys are in a downward position.

Bronze Phospher strings are best suited for a standard acoustic guitar which Notably has a solid headstock with horizontal tuning keys. These guitars generally have an adjustable truss rod in the neck and aid in support of the string tension pull. Bronze strings allow a less pull on the neck while allowing ease of tuning and a somewhat brighter sound that nylon and warmer than steel. Steel strings can be used on a standard acoustic, but I don't recommended using them.

There are many style and gauge strings available for all guitars, when in doubt go to your local music store and ask for help, its free, with the purchase of a set of strings.
