Answer Posted / Radhe Shyam
A power amplifier increases the power of an electrical signal, while a voltage amplifier increases the amplitude (voltage) of an electrical signal. Power amplifiers have a high power output and are used to drive loudspeakers or other loads that require large amounts of power. In contrast, voltage amplifiers have a lower power output but can achieve higher voltage gains. They are commonly used for sensitive instruments or laboratory applications.
