# Transistor Output characteristics (CE)

Objective

Plot the output characteristic curve of a transistor. Collector is connected to PV1 through a 1K resistor.

Procedure

- Set base voltage to the 1 volt and START.

- Repeat for different base currents.

Discussion

The characteristic curves for different base currents are shown in figure. The collector current is obtained from the voltage difference across the resistor.

The base current is set by setting the voltage at one end of the resistor, the other end is connected to the transistor base. The value of base current is calculated by, . If A2 is not connected, the code assumes 0.6 volts at the base to calculate the base current.
