Transistor Amplifier

A transistor amplifier is a device that boosts the strength of weak electrical signals, allowing them to drive larger devices like speakers or speakers. It uses a small input signal to control a much larger current flowing through the transistor, similar to how a small push on a lever can move a heavy object. This process maintains the original signal’s shape but increases its power, making it useful in audio systems, radios, and many electronic devices to enhance sound, video, or data signals for better performance and clarity.
