Using Kirchhoff's rules, find the following. $({}_1=70\mathrm{.}8V,{}_2=61\mathrm{.}8V,$ and ${}_3=79\mathrm{.}8V.)$

$$

$($i$)$

$($a$)$ the current $($in mA $)$ in each resistor shown in the figure above

$I_{R_1}=$

Your incorrect answer may have resulted from roundoff error. Make sure you keep extra significant figures in intermediate steps of your calculation. mA

$I_{R_2}=mA$

$I_{R_3}=mA$

$($b$)$ the potential difference between points $c$ and $f($Give the magnitude of your answer in volts and select the point of highest potential.$)$

magnitude of potential difference $$ v

point at higher potential
