find the amplitude of the current i0 through the voltage source.

To understand the use of phasors in analyzing a parallel AC circuit.Phasor diagrams, or simply phasors, provide a convenient graphical way of representing the quantities that change with time along with  .This makes them useful for analyzing AC circuits with their inherent phase shifts between voltage and current. If a quantity I(t) changes with time as   , a phasor is a vector whose length represents the amplitude Io(see the diagram). This vector is assumed to rotate counterclockwise with angular speed  ; that way, the horizontal component of the vector represents the actual value I(t) at any given moment.In this problem, you will use the phasor approach to analyze an AC circuit.

In answering the questions of this problem, keep the following in mind.

For a resistor, the current and the voltage are always in phase.

For an inductor, the current lags the voltage by .

For a capacitor, the current leads the voltage by .

I need help with this problem. I understand you cant askmultiple questions but I just need someone to help me get startedwith this problem. Please help!

Two 350.0-W speakers, A and B, are separated by a distance D = 3.41m. The speakers emit in-phase sound waves at a frequency f =11800.0 Hz. Point P1 is located at x1= 4.51 m and y1 = 0 m; pointP2 is located at x2 = 4.51 m and y2 = –?y.
a) Neglecting speaker B, what is the intensity, IA1 (in W/m2), ofthe sound at point P1 due to speaker A? Assume that the sound fromthe speaker is emitted uniformly in all directions.
b) What is this intensity in terms of decibels (sound level,ßA1)?
c) When both speakers are turned on, there is a maximum in theircombined intensities at P1. As one moves toward P2, this intensityreaches a single minimum and then becomes maximized again at P2.How far is P2 from P1, that is, what is ?y? You may assume that L>> y and that D >> y, which will allow you to simplifythe algebra by using (a±b)1/2 ˜ a1/2 ± 0.5b/a1/2 when a >> b.
