What is the primary function of an operational amplifier in a circuit?
Step 1: Understand what an operational amplifier (op-amp) is. It is an electronic component that can amplify electrical signals.
Step 2: Know that the main job of an op-amp is to increase the voltage of a signal. This means it makes weak signals stronger.
Step 3: Recognize that op-amps are used in many devices, like audio equipment, to improve sound quality by amplifying sound signals.
Step 4: Remember that op-amps can also be used in other functions, like filtering signals or performing mathematical operations, but their primary function is to amplify voltage.
