Determine the resistance R₀₁ and R_02, equivalent resistance of the circuit, (a combination of resistances R₁ = 5 Ω, R₂ = 2 Ω and R₃ = 2 Ω which are connected in serial and parallel in the circuit as shown below) and the total current I flowing in the circuit, and currents I₁ and I₂ flowing through resistances R₂ and R₃. It is also known that the power of the circuit is U = 12V.
