Current Amplification

Current amplification is a process in electronic devices where a small input current controls a much larger output current. Think of it as a tiny person, the input signal, directing a much bigger flow of electricity (output) without directly handling all the power. This is essential in amplifiers, like audio or radio devices, where weak signals need to be boosted to usable levels. The device achieves this by using components like transistors, which allow a small input current at one terminal to control a larger current flow between two other terminals, effectively increasing the current at the output.
