Voltage Amplifier

A voltage amplifier is an electronic device that increases the strength of an electrical voltage signal without significantly changing its other characteristics. It takes a weak input signal, such as from a microphone or sensor, and boosts its voltage level so it can be used to drive other devices like speakers or recording equipment. Essentially, it makes a small electrical signal larger and more powerful while preserving the original signal’s shape and details, enabling clearer and louder sound, video, or data transmission in various electronic systems.
