Charging and Discharging of a Condenser with power supply and 2 multi range meters Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12196
Indian Lab Suppliers supplies the Charging and Discharging of a Condenser with power supply and 2 multi range meters (Product ID: 12196) as part of its electronics engineering lab equipment range. It is a board for plotting the charge and discharge curves of a capacitor (condenser) and finding the R-C time constant.
Quick Answer
A continuously variable 0–20 V DC, 25 mA regulated supply, four electrolytic capacitors and three SPDT switches are built in, with a 3½-digit DC voltmeter (2 V / 20 V) and a 3½-digit DC current meter (20 mA). Timing readings against a digital stop clock, students plot voltage and current against time while charging and discharging, and find the time constant from each graph: on charge the voltage reaches about 63% of the supply in one RC, and on discharge it falls to about 37%. Electrolytic capacitors are polarised; connect them the right way round.
