Wien Bridge

Wien Bridge
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.
