In the circuit shown below $\mathcal{E}$ = 81.0 V, $R_5$ = 4.00 $\Omega$, $R_3$ = 2.00 $\Omega$, $R_2$ = 2.20 $\Omega$, $I_5$ = 8.10 A, $I_4$ = 6.00 A, and $I_1$ = 13.3 A. Find the current through $R_2$ and $R_3$, and the values of the resistors $R_1$ and $R_4$.
$I_2$ = Based on the known variables, which two junctions should you consider to find the current $I_2$? A
$I_3$ = Based on the known variables, which two junctions should you consider to find the current $I_3$? A
$R_1$ = Which loop will give you an equation with just $R_1$ as the unknown? Did you follow the sign convention for the potential difference across each element in the loop? $\Omega$
$R_4$ = Which loop will give you an equation with just $R_4$ as the unknown? Did you follow the sign convention for the potential difference across each element in the loop? $\Omega$
