This paper presents a unique idea to visualise the charging and discharging cycle for a set of capacitors connected in parallel in an experimental kit. The variation in voltage with time during the charging and discharging of capacitors is recorded as pulses and can be observed on the DSO screen. The time scale of the recorded data can be expanded for convenient and accurate measurement of pulse width. The method can also be used for the measurement of an unknown value of capacitance of a capacitor instead of manual counting of flashes of neon bulb in the conventional kit.
