Wien Bridge

quick overview :

Measurement of Capacitance byWien Bridge Features: The board consists of the following built-in parts: 1. ±12V D.C. at 100mA, IC regulated Power Supply internally connected. 2. 1 KHz Sine Wave Oscillator. 3. Audio Amplifier and speaker for null detection. 4. Three decade resistances, single dial in steps of 100 Ohm, Total 1K each, to form arms of a bridge. 5. Decade resistance, Two dials of 10 Ohm & 100 Ohm, total 1100 Ohms to form arms of bridge. 6. Decade Standard Capacitance, selectable by a band switch to form the one arm of the bridge. 7. Unknown capacitor and adequate no. of other electronic components. 8. Mains ON/OFF switch, Fuse and Jewel light.
