please answer questions #3 & the summary and conclusion

Parallel Circuit (1) In a parallel circuit, does the current through the resistors or voltage across the parallel resistors remain the same? Support your answer with numbers from your data and Equ. J. Since the last two columns almost have the sare Values, in a parallel lirlut the vottage across resistars does remain the same. $I_{2}I_{3}?=R_{3}R_{2}??I_{3}R_{3}=I_{2}R_{2}$ (2) Using Equ. $T$, compare your observed values to the expected total current $I_{1}$. Find the percentage deviation of the "worst case' value from the expected value. Calculated current I $I_{1}=$ worst observed curient $I_{1}=$ $q_{0}=calcurated(Calculiated-10bserved)?×100$ AC circuit: $=23.323.3?23.4?×100=4.2919$. (3) Compare the values $2?V_{2}$ and $V_{2pak.}$. Are they equal? (4) The AC circuit used in this exercise is called a voltage divider. Why? The recisen is because H's able. to divicle the total Vutage into ercictional peraicans of canstant rectio. $V=IR?I=V/R$ Summary and Conclusions
2-2: AC series circuits Set up the circuit shown below. Switch $AM$ and $VM$ to ac mode. Use $AC$ power supply. Set $V_{s}=3V$ by measuring it with the VM across the source. Set $R_{2}=1000$ Ohms. $R_{1}$ values are given in the table below. Measure the rms current $I$ (rms) through $R_{1}$ and $R_{2}$. Measure the rms voltage $V_{2}(ms)$ across $R_{2}$. Measure the peak voltage $V_{2peak}$ across $R_{2}$ with the oscilloscope. Keep $Vs=3.0V$ all the time. Compare the values $2?V_{2}(rms)$ and $V_{2peak}$ (the last two columns in the table below). Plot $1(rms)$ versus $V_{2}$ (rms). Fit it to a linear curve and find the slope, $S$. Calculate $R_{2}=1/S$.
Preliminary Observations: Set up the circuit shown below: use 1 voltmeter, 3 ammeters, 3 resistance boxes and a DC power supply. Set $V_{s}=7.00V,R_{1}=R_{2}=R_{3}=200$; $R_{23}=R_{2}+R_{3}R_{2}R_{2}?=R_{23}I=R_{2}V_{2}?=R_{1}R_{1}+R_{23}??$ Calculate the expected current $I_{1}$ : $I_{1}=0.355m_{A}$ Calculated current $I_{1}=23.33m_{A}$ Observed current $I_{1}=23.41mA$ Percent difference: $0.32%$ Data Record: the currents $I_{1},I_{2},I_{3}$ for the R-values in the table. Record currents in $mA$. Calculate and record: $(I_{2}+I_{3}),l_{2}/L_{2}$, and $R_{2}/R_{3}$. Compare the values in the last 2 columns. Are they equal?
