I want to know the idea u used to find loop 1 and 2

• Loop 1 (Mesh 1): This is the leftmost closed path in the circuit. It includes the top 6V voltage source, the 2Ω resistor, the 3Ω resistor, and the middle 6V voltage source. We assign a circulating current, $i_1$, to this loop, typically in a clockwise direction for consistency.
• Loop 2 (Mesh 2): This is the rightmost closed path in the circuit. It includes the middle 6V voltage source, the 3Ω resistor, the 1Ω resistor, and the 6Ω resistor. We assign another circulating current, $i_2$, to this loop, also typically in a clockwise direction.

These are chosen as independent loops, meaning that each loop contains at least one component that is not part of any other chosen loop. By defining these mesh currents, we can write KVL equations for each loop, and then solve the resulting system of equations to find the values of $i_1$ and $i_2$. Once these mesh currents are known, any branch current in the circuit can be determined as a combination of $i_1$ and $i_2$.
