Experiment No. 2

Procedure

* Connect the circuit. R1 and R2 must be set for maximum resistance before power is supplied.

* Connect the power supply, adjust R1 for 10 μA base current and adjust R2 to maintain VCE at 6V, Measure and record IC in the table below.

* Repeat the measurement for every value of IB given in the table.

* Calculate the current gain (beta) for every measurement.
