To do this experiment, you will need the following: Large-value capacitors are required for this experiment to produce time constants slow enough to track with a voltmeter and stopwatch. CAUTION: Be warned that most large capacitors are of the electrolytic type, and they are polarity sensitive!
Proper containment, fusing, and preventative maintenance can help to minimize these hazards. High voltage capacitors can benefit from a pre-charge to limit in-rush currents at power-up of HVDC circuits. This will extend the life of the component and may mitigate high voltage hazards.
Capacitors used within high energy capacitor banks can violently explode when a fault in one capacitor causes sudden dumping of energy stored in the rest of the bank into the failing unit. And, high voltage vacuum capacitors can generate soft X-rays even during normal operation.
This document describes an experiment on charging and discharging of capacitors. It involves using a 100μF capacitor, 1MΩ resistor, 9V battery, and multimeter. The procedure is to connect these components in a circuit and take voltage readings across the capacitor at 20 second intervals as it charges.
As opposite charges accumulate on the plates of a capacitor due to the separation of charge, a voltage develops across the capacitor due to the electric field of these charges. Ever-increasing work must be done against this ever-increasing electric field as more charge is separated.
[ View Experiment] A capacitor is an electrical device that can store energy in the electric field between a pair of conductors. Capacitance is the ability of a body to hold an electrical charge. A capacitor is an electrical/electronic device that can store energy in the electric field between a pair of conductors (called "plates").
