Question

Given the following circuit:

RT = 10Ω --> Is = 20V / 10Ω --> Is = 2A --> Is = IR1 = 2A

Since I1 = I2 +  I3, therefore, when the circuit flows to the end, I2 + I3 = I1 once more, making IR2 to have the same current as IR1, therefore IR2 = 2A

I3 = Is *  (R3 / (R3 + R4 + R5)) --> 2A * (6Ω / (6Ω + 1Ω + 2Ω)) --> 2A * (6/9)  --> I3 = 4/3A  --> IR3 = 2/3A

I3 = IR4 = 4/3A

I3 = IR5 = 4/3A

Can you check if its correct?
