Amplifier

An amplifier is an electronic device that increases the power of a signal, making it stronger. Think of it like a microphone that boosts your voice so that a crowd can hear you clearly. Amplifiers are used in various applications, such as in sound systems to enhance audio quality, in radios to improve signal reception, and in televisions for better picture quality. Essentially, they take a weak electrical signal and make it large enough to drive speakers or other outputs, ensuring better performance in electronic devices.
