So I have to do a phasor diagrams for this 4 circuits. Number 2 and 4 I think I've done it correctly (but i can be wrong). Number 1 I just draw Uab, I2 and I3 and i dont know what to do next, and number 3 I just dont know how start it ( Ul or U) and how draw Uc and Ur.

English is not my 1st language, but i think you will understand.

Am I done 2 and 4 correctly? If not what did i do wrong? and how to make 1 and 3?
