1. The problem statement, all variables and given/known data In the network of sinusoidal current, as shown in the figure, the current i2 is phase delayed for the angle of 3π/4 behind the current i. In the moments in which the current i2 is minimal, current value of current i1 is sqrt(2) A. This value is two times lower than the maximum value of the current i1, and in those moments current i1 and growing. Calculate the effective value of the current I.

The attempt at a solution capture screen Is there any way to find the angle Φ2 since I know that in the moments when i2 is minimal value of the current i1 is sqrt(2)?
