Measurement of Capacitance by Wien Bridge with power supply and oscillator Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12244
Indian Lab Suppliers supplies the Measurement of Capacitance by Wien Bridge with power supply and oscillator (Product ID: 12244) as part of its electronics engineering lab equipment range. It is a board for measuring unknown capacitance with the series and parallel forms of the Wien bridge.
Quick Answer
A built-in 1 kHz sine oscillator drives the bridge, and an audio amplifier with speaker gives an audible null. The arms are made from three single-dial decade resistances (100 Ω steps, 1 kΩ each), a two-dial decade resistance (10 Ω and 100 Ω steps, 1100 Ω total) and band-switched standard capacitances. Students balance the series Wien bridge and then the parallel Wien bridge against the unknown capacitor and compare the two results. A ±12 V DC, 100 mA IC-regulated supply is connected internally.
