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.
