For the part of the circuit of sinusoidal circuit given below, the following data is given (effective values): $E=10V,I_g=2\sqrt 3 A,I_2=2A$ .

Impedance of conductor is $Z_C=5\Omega$ .

Current I_g

is leading in phase with regards to

for

, and

is running late in phase with regards to I_2

for $\pi/2$ .

Evaluate effective value of voltage $U_{10}$ .

I think that the following intuitive solution is completely incorrect:

By using potential of nodes method on branch 1-0, if we set 0 node as referent, we have:
$\underline{V_1}\frac{1}{\underline{Z_C}}=\frac{\underline{E}}{\underline{Z_C}}\Rightarrow \underline{V_1}=\underline{E}$

Could someone explain why this solution is incorrect?

What is a correct approach?
