Product Code : SCL-PL-11834
Capacitor (Charging and Discharging) (SKU SCL-PL-11834) is a practical set for studying how a capacitor charges through a resistor and then discharges, with its own DC power supply, multimeter, resistors and capacitor. It is intended for Class 12 physics, B.Sc. electricity practicals and electronics courses in polytechnics and ITIs. The RC set is manufactured by Science Lab Supplies on its Saha, Ambala site (Plot 448, HSIIDC Industrial Area, India), and that site handles quotations for schools, colleges, tender contractors and distributors.
Specifications
Supply rating, component values and wiring for the charging and discharging set are tabulated below. In short, a 0–20 V DC, 1 A supply charges a 1000 µF capacitor through a 10 kΩ or 100 kΩ resistor while the multimeter tracks the voltage, and outlet boards with six pairs of leads complete the circuit.

Applications and Experiments for the Capacitor Charging and Discharging Set
Students can record capacitor voltage against time while charging and discharging, plot the exponential curves and find the time constant RC. Swapping the 10 kΩ resistor for the 100 kΩ one shows how resistance slows the process, which makes the set a clear introduction to RC circuits.
- Class 12 physics: capacitors and capacitance, energy stored in a capacitor.
- B.Sc. practical: charging and discharging curves and the time constant of an RC circuit, with a second meter such as the Digital Voltmeter (0–20 V DC) across the resistor.
- Polytechnic and ITI electronics: RC timing behaviour.
With the 1000 µF capacitor, RC works out to about 10 s with the 10 kΩ resistor and about 100 s with the 100 kΩ resistor, so readings can be timed with a School Digital Stopwatches unit reading to 1/100 s.
Standard Scope of Supply
The set is supplied with the 0–20 V DC, 1 A power supply, a multimeter, the 10 kΩ and 100 kΩ resistors, a 1000 µF capacitor, outlet boards, six pairs of red and black conducting wires and a capacitor charging and discharging demonstration table.
Packing, MOQ and Lead Time
Quotes are available from one set upwards, including enough sets for a full practical batch. The packing method, delivery time and price are set out on each quotation for the quantity you give, and other electricity items from the physics range may be included alongside.
With its Importer-Exporter Code, Science Lab Supplies can ship to buyers in Egypt, Iraq, Nigeria, Kenya, Ghana and Ethiopia. RC practical sets can be priced once you share numbers on the contact page or send the enquiry cart; bid rules for colleges sit on the lab tender page.
Frequently Asked Questions
What can students measure with the Capacitor (Charging and Discharging) set?
They can record voltage against time as the 1000 µF capacitor charges and discharges, plot the curves and estimate the RC time constant for each resistor.
Is a power supply included?
Yes. A 0–20 V DC, 1 A power supply is part of the set, together with a multimeter and the connecting leads.
Is Science Lab Supplies the manufacturer or a trader?
Each charging and discharging set is put together at the Science Lab Supplies factory in Saha, Ambala, India, and the quotation is issued from the same factory, so no reseller stands between you and the manufacturer.
Can it be ordered for a college physics lab tender?
Yes. Share the tender specification, the delivery location and the number of sets, and Science Lab Supplies will prepare an item-wise quotation matching the components listed here.
