 ===== Procedure: ===== ===== Procedure: =====
 Load the captured data in to a spreadsheet program like Excel and calculate the current. Plot the current vs. the voltage across the transistor (V<​sub>​BE</​sub>​). No current flows in the reverse direction. In the forward conduction region, the voltage, current relationship is logarithmic. If the current is plotted on a log scale the line should be straight. Load the captured data in to a spreadsheet program like Excel and calculate the current.
