Applying Kirchhoff's laws, we can write: - The sum of voltages in a closed loop is equal to zero. - The sum of currents at a node is equal to zero. Using the first law, we can write: 4V - 2.5Ω*I - 1.5Ω*I - 1Ω*I = 0 or I = 4V / (2.5Ω + 1.5Ω + 1Ω) = 0.0077 A Therefore, the current through R₆ is 0.0077 A.
