F.E.T. Characteristics with power supply and 3 meters (C.R.) Manufacturer,Supplier and Exporter in India
.png)
Product Code : SCL-EELE-12167
Indian Lab Suppliers supplies the F.E.T. Characteristics with power supply and 3 meters (C.R.) (Product ID: 12167) as part of its electronics engineering lab equipment range. It is a self-contained board for plotting the drain and transfer characteristics of a field effect transistor and finding its parameters.
Quick Answer
A single FET is powered by two continuously variable supplies, 0–20 V DC and 0–12 V DC, each 50 mA, and read on two 3½-digit DC voltmeters (0–20 V) and a 3½-digit DC current meter (0–20 mA). Students measure IDSS, plot drain current against drain voltage for fixed VGS and against gate bias for fixed VDS, show the FET acting as a voltage-variable resistance, and calculate rd, gm and μ = gm × rd at an operating point.
