Total resistance R = R1 + R2 = 4 + 4 = 8 ohms. Current I = V/R = 12V / 8 ohms = 1.5 A.

Total resistance R = R1 + R2 + R3 = 2Ω + 4Ω + 6Ω = 12Ω. Using Ohm's law, I = V/R = 24V / 12Ω = 2A.

Using Ohm's law, I = V/R = 9V/3Ω = 3A.

Total resistance R = 1/(1/3 + 1/3) = 1.5Ω; I = V/R = 9V/1.5Ω = 6A.

In a parallel circuit, the total current is the sum of the currents in each branch: I_total = I1 + I2 = 2 A + 3 A = 5 A.
