Consider the circuit shown below. (Due to the nature of this problem, do not use rounded intermediate values in your calculations\---including answe
$R_4 = 2 \Omega$
$R_1 = 7 \Omega$
$+

$V_2 = 5 V$
$V_1 = 13 V$
$R_2 = 7 \Omega$
$I_5$
$I_2$
$R_3 = 2 \Omega$
$I_3$
(a) Find $I_1$, $I_2$, $I_3$, $I_4$, and $I_5$ (all in A). (Indicate the direction with the signs of your answers.)
$I_1 = \boxed{} A$
$I_2 = \boxed{} A$
$I_3 = \boxed{} A$
$I_4 = \boxed{} A$
$I_5 = \boxed{} A$
(b) Find the power supplied by the voltage sources (in W).
$\boxed{} W$
(c) Find the power dissipated by the resistors (in W).
$\boxed{} W$
