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. Science Lab Supplies manufactures the set in Ambala, at its Plot 448 factory in the HSIIDC Industrial Area, Saha, and delivers it straight to schools, colleges, tender contractors and distributors.
Specifications
A 0–20 V DC, 1 A power supply charges a 1000 µF capacitor through either a 10 kΩ or a 100 kΩ resistor, and the multimeter tracks the voltage as it rises and falls. Outlet boards and six pairs of red and black leads make the circuit quick to assemble.

Applications and Experiments for the Capacitor Charging and Discharging Set
Students 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.
- 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 taken with an ordinary stopwatch.
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.

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?
Science Lab Supplies is the manufacturer, not a reseller. Sets are put together at the Saha, Ambala factory in India, and the quotation you receive comes straight from that factory.
Can it be ordered for a college physics lab tender?
Yes. Share the tender specification and the number of sets for an item-wise quotation matching the components listed here.
