-The waveform generator should be configured for a 100 Hz triangle wave with 6 volt amplitude peak-to-peak and 0 offset. The differential scope channel 2 (2+, 2-) measures the current in the resistor (and in the transistor). Scope channel 1 (1+) is connected to measure the voltage across the transistor. The current flowing through the transistor, is the voltage difference ​1+ and 1- divided by the resistor value (1KΩ).+The waveform generator should be configured for a 100 Hz triangle wave with 6 volt amplitude peak-to-peak and 0 offset.
