For the given circuit, assuming a series resistor of 220 ohms and a silicon diode, create a table of readings and plot a graph of If vs Vf.

Here are the answers to your questions based on the provided circuit diagram.

Assumptions:

• The series resistor $R = 220 \, \Omega$.
• The diode is a silicon diode, with a typical forward voltage drop ($V_f$) starting around $0.7 \text{ V}$ and increasing slightly with current.
• The values for $V_f$ and $I_f$ are estimated based on these assumptions, as no specific diode characteristics or experimental data were provided.

a) Tabulate your readings

$V_s$ (V)	$V_f$ (V)	$I_f$ (mA)
1.5	0.70	3.64
3.0	0.73	10.32
4.5	0.76	17.00
6.0	0.79	23.68
7.5	0.82	30.36

b) Plot a graph of $I_f$ and $V_f$
To plot the graph, you would use the data from the table above.

• Plot $V_f$ on the x-axis (horizontal axis) and $I_f$ on the y-axis (vertical axis).
• The points to plot are: $(0.70 \text{ V}, 3.64 \text{ mA})$, $(0.73 \text{ V}, 10.32 \text{ mA})$, $(0
