9. For the following circuit with a current meter, use Mesh Analysis to calculate the mesh or loop currents ($I_1$, $I_2$, & $I_3$) and find the current through the meter if the meter is 100 ohms resistance. (Partial credit will be given. To get full credit, you must show your work. i.e. matrices, developed equations, etc.) Also find $V_{R3}$.
$V_T = 3V$
$R_1 = 330\Omega$
$R_2 = 1k\Omega = 1000\Omega$
$R_3 = 680\Omega$
$R_4 = 470\Omega$
