What is the primary use of an oscilloscope in electronics?

The primary use of an oscilloscope in electronics is to visualize and measure waveforms. This important tool allows engineers and technicians to observe electrical signals in a graphical format over time, making it easier to analyze the behavior of circuits, identify signal characteristics, and troubleshoot issues. By providing a visual representation of voltage changes across time, oscilloscopes enable users to see parameters such as amplitude, frequency, and distortion, which are crucial for understanding and diagnosing the performance of electronic systems.

Additionally, the other options do not align with the primary function of an oscilloscope. Amplifying electrical signals is the role of amplifiers, storing electric charge pertains to capacitors, and converting AC to DC is the function of rectifiers. These components serve different purposes within electronic circuits, underscoring the unique role of the oscilloscope in waveform analysis.
