Educational trainer


Experimental Training Board has been designed specifically for the measurement of inductance of a coil by Anderson Bridge. It includes audio amplifier with speaker for null detection (Instead of head phone) and one KHz sine wave oscillator instead of externally used decade audio frequency generator The board is absolutely self contained and requires no other apparatus.

Practical experience on these boards carries great educative value for Science and Engineering Students.

The board consists of the following built-in parts :

01. Anderson Bridge circuit with arms values

02. Potentiometer for varying one arm

03. Three different value inductances     

04. Potentiometer with calibrated dial

05. Five capacitors selected by a band switch

06. Auio Amplifier with its IC regulated Power Supply

07. One KHz Sine Wave Oscillator with its IC regulated Power Supply

08. Speaker.

09. Mains ON/OFF switch, Fuse and Jewel light.
