Answer 2

please help me

Answer 3

here we can apply this equation:
\[{\text{rot }}{\mathbf{E}} = {\mathbf{0}}\]
to each of the three nets of your circuit

Answer 6

please wait a moment, I have to write the necessary equations

Answer 7

here are the requested equations:
\[\Large \left\{ \begin{gathered}
- {V_1} + {R_1}{I_1} + {R_2}\left( {{I_1} - {I_3}} \right) + {R_3}\left( {{I_1} - {I_2}} \right) = 0 \hfill \\
\hfill \\
{R_3}\left( {{I_2} - {I_1}} \right) + {R_4}\left( {{I_2} - {I_3}} \right) + {R_5}{I_2} = 0 \hfill \\
\hfill \\
- {V_2} + {R_6}{I_3} + {R_2}\left( {{I_3} - {I_1}} \right) + {R_4}\left( {{I_3} - {I_2}} \right) = 0 \hfill \\
\end{gathered} \right.\]
where:
