Capacitor (Charging and Discharging)
Capacitor (Charging and Discharging) (Product Code: SCL-231/036) is a capacitor experiment set used to show how a capacitor charges and discharges through a resistor in school and college physics practicals. It pairs a 1000 µF capacitor with 10 kΩ and 100 kΩ resistors and a 0–20 V DC, 1 A power supply, so students can compare a fast and a slow RC curve with the multimeter. The set is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Capacitor Charging and Discharging Set Used For?
Students build a series circuit of the power supply, one resistor and the 1000 µF capacitor on the outlet board, then read the capacitor voltage with the multimeter at regular time intervals while it charges. Disconnecting the supply and letting the capacitor empty through the same resistor gives the discharge curve. Both curves are exponential, and their pace is set by the time constant τ = RC.
With the listed parts, RC works out to about 10 seconds for the 10 kΩ resistor and about 100 seconds for the 100 kΩ resistor, which is slow enough to time by hand. This makes the set a practical electricity experiment kit for school labs: the class can see that a tenfold larger resistance gives a tenfold slower curve. Keep the supply below the voltage marked on the capacitor, observe any polarity markings, and discharge the capacitor through a resistor before handling it.
What to Specify When Ordering
- Number of sets required, one per student group.
- Whether you also need a timing device, as none is itemised in the set.
- Spare red and black connecting wires for additional circuits.
OEM Manufacturer
Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM (original equipment manufacturer) of the Capacitor (Charging and Discharging) set. It is produced at the company’s own licensed factory at Saha, Ambala, Haryana, India, and delivered straight from the factory to schools, colleges, institutions, dealers and importers.

Frequently Asked Questions
What is included in the Capacitor (Charging and Discharging) set?
The Capacitor (Charging and Discharging) set includes a 0–20 V DC, 1 A power supply, a multimeter, 10 kΩ and 100 kΩ resistors, a 1000 µF electronic capacitor, an outlet board, six pairs of red and black conducting wires and a capacitor charging and discharging demonstration table.
What time constants can be studied with this capacitor set?
With its 1000 µF capacitor, the Capacitor (Charging and Discharging) set gives a time constant of about 10 seconds with the 10 kΩ resistor and about 100 seconds with the 100 kΩ resistor, so students can compare two clearly different RC curves.
What power supply does the Capacitor (Charging and Discharging) set use?
The Capacitor (Charging and Discharging) set (SCL-231/036) includes its own adjustable power supply rated 0–20 V DC at 1 A. Start at a low voltage and stay within the voltage marked on the capacitor.
How should the capacitor be handled safely?
Before touching the leads of the Capacitor (Charging and Discharging) set, discharge the 1000 µF capacitor through one of the resistors and check with the multimeter that its voltage has fallen. Observe any polarity markings and never exceed the capacitor’s marked voltage.
Who manufactures the Capacitor (Charging and Discharging) set?
The Capacitor (Charging and Discharging) set, code SCL-231/036, is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM at its own licensed factory at Saha, Ambala, Haryana, India. Quotations and repeat orders come directly from the manufacturer.
