Question

1. Connect the circuit shown in Figure 6-1. 5.0V 5.0V 100? 2N3904 1k? Figure 6-1 2. Switch the input voltage to 0 V using the switch at the base of the transistor. Observe the state of the LED. 3. Measure and record the base current $I_B$, collector current $I_C$ and the collector-emitter voltage $V_{CE}$. 4. Switch the input voltage to 5 V using the switch at the base of the transistor. Observe the state of the LED. 5. Measure and record the base current $I_B$, collector current $I_C$ and the collector-emitter voltage $V_{CE}$. 6. Verify that the BJT is saturated using the equation $I_B > \frac{I_C}{\beta_{min}}$ Note: You will have to acquire $\beta_{min}$ from the datasheet of the BJT. 7. Simulate this experiment on MultiSim to verify your results.
