What are the differences between acoustic and electric strings, and how do they affect the sound and playability of a guitar?

Acoustic strings are typically made of bronze or phosphor bronze, while electric strings are usually made of nickel or stainless steel. Acoustic strings produce a warmer, more resonant sound, while electric strings have a brighter, crisper tone. The differences in material and construction affect the playability of the guitar, with acoustic strings requiring more finger strength and electric strings being easier to bend and manipulate for techniques like vibrato.
