dding R3 pulled the floating transistor base down, to prevent accidentally triggering the transistor. Afterward, the rcuit was still able to light D1 when SW1 was closed. Which answer best explains why that happened? O At 100KQ, the resistance of R3 is powerful enough to pull the base all the way down to ground, creating a path for current through D1, causing the LED to light. O R3 has 100KQ of resistance, which diverts most of the current from the rest circuit. This allows the transistor to keep control of the circuit, which keeps the base from floating and lights the LED when SW1 is closed. O Adding such high resistance between the transistor base and ground essentially insulates the transistor connection. This prevents accidental triggering of the transistor and helps the circuit function more reliably. O R3 has very high resistance, so the transistor base is only pulled down a little bit. When SW1 is closed R1 still pulls the base high enough to trigger the transistor because R1 has ten times less resistance than R3.

Context: The results obtained in table 4.1 were gathered using a multimeter conducting on a circuit board. The results obtained in table 2.1 was obtained through theoretical calculation, and table 2.3 was obatined through a circuit simulation software. The values in tables 2.1 and 2.3 are identical. All three tables ask for Vo and I. Table 4.1 shows slight discrepancies, explain why, including many possible causes. The second question asks to recalculate Vo and I using the resistor value 5.1k ohm, the value used to obatin table 4.1. Where tables 2.1 and 2.3 were obtained with a resistor value of 5.0k ohm. The calculation is included in part 4(c). Include all steps and information. Thank you very much.

From your understanding, what is the differnece between a grounding wire and a grounded wire? I answered this way ... Grounding wire is connecting to ground or to a conductive body extends the ground connections. Whereas the grounded wire is connected to earth or to some conducting body that serves inplace of the earth. The replied I got from a classmate "I feel your definitions here aren't exactly different. The first describes connecting to ground and the second to earth. Those are one and the same. Am I missing your meaning, or do I have that correct?" Is he right or am I really missing the subject? Please reply me soon. Thank you
