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 mA 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.
