Current amplification factor of a transistor with Power Supplies and 3 digital meters (C.R.) Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12290
Indian Lab Suppliers supplies the Current amplification factor of a transistor with Power Supplies and 3 digital meters (C.R.) (Product ID: 12290) as part of its electronics engineering lab equipment range. It determines the current amplification factor of a transistor graphically from measured base and collector currents.
Quick Answer
A potentiometer sets the base current, read on a 2 mA range 3½-digit digital meter, while the collector current is read on a 200 mA range digital meter and the collector voltage on a 20 V range digital voltmeter. Supplies are a fixed 6 V DC and a 0-6 V DC continuously variable source, both 100 mA. Plotting collector current against base current gives a line whose slope is the current gain (β = ΔIC/ΔIB). The transistor is mounted on a heat sink, and the board needs no other apparatus.
