What is the purpose of a graduated cylinder?

The purpose of a graduated cylinder is to measure volumes of liquid with high precision. Graduated cylinders are designed specifically for accurately measuring the volume of liquids in a laboratory setting, thanks to their clear markings along the side that indicate the volume. The shape and design of the graduated cylinder provide a stable container that minimizes inaccuracies caused by meniscus errors, making them more reliable for precise measurements compared to other containers like beakers or flasks.

In contrast, the other options do not align with the function of a graduated cylinder at all. Measuring torque requires a completely different tool designed for that purpose, capturing electronic waveforms involves instruments like oscilloscopes or signal analyzers, and analyzing electronic circuit performance is achieved with devices such as multimeters and oscilloscopes, not a graduated cylinder. Each of these functions requires specialized equipment tailored to the specific type of measurement or analysis, whereas the graduated cylinder remains focused on liquid volume measurement.
