## Homework Statement

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.

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)?
