F.E.T. Characteristics Educational Trainer For Electrical Lab Training

specifically to study the characteristics of a field effect transistor. The board is absolutely self contained and requires no other apparatus. Practical experience on this board carries great educative value for science and engineering students. Object: To study the characteristics of field effect transistor : 01. Measurement of i dss. 02. Plot the static drain characteristics of fet (a) Drain current v/s drain voltage characteristics for different fixed values of vgs. (b) Drain current v/s gate bias characteristics for different fixed values of vds. 03. Calculate the fet parameters (drain dynamic resistance r , mutual conductance g , and amplification factor m) at a given operating d m point. Features: The board consists of the following built-in parts: 01. 0 to 20v d. C. At 50ma, continuously variable power supply. 02. 0 to 12v d. C. At 50ma, continuously variable power supply. 03. Two d. C. Voltmeters, 65mm rectangular dial to read 0-20v. 04. D. C. Milliammeter, 65mm rectangular dial to read 0-20ma. 05. Field effect transistor. 06. Adequate no. Of other electronic components. 07. Mains on/off switch, fuse and jewel light. The unit is operative on 230v ±10% at 50hz A. C. mains. Adequate no. Of patch cords stackable from rear both ends 4mm spring loaded plug, length ½ metre. Good quality, reliable terminal/sockets are provided at appropriate places on panel for connections /observation of waveforms. Strongly supported by detailed operating instructions, giving details of object, theory, design procedures, report suggestions and bookn references. Weight : 3 kg.
