Consider the circuit depicted below. By using the two following facts: (i) the voltage drop across a resistor is $V=IR$ and (ii) the sum of all voltage drops in a closed loop sum to zero, The currents $i_1,i_2$, and $i_3$ are determined from the $3\times 3$ system. $\begin{array}{r}\left(R_1+R_2\right)i_1?R_2{i}_2=v_1\\ ?R_2{i}_1+\left(R_2+R_3+R_4\right)i_2?R_4{i}_3=0\\ ?R_4{i}_2+\left(R_4+R_5\right)i_3=?v_2\end{array}$ Let $R_1=R_2=R_3=R_4=R_5=1\mathrm{ohm}$, and let $v_1=5$ volts and $V_2=?6$ volts. (a) Rewrite this system of equations in matrix form. That would mean have A17 and the bector in A18.
