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. 1Â 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.
