## Homework Statement

Use source transformation on the voltage source and series-connected impedance for the circuit shown here to find the equivalent current source and parallel-connected impedance. Continue the simplification by combining the two parallel current sources into an equivalent current source, and by combining the three parallel impedances into a single equivalent impedance.

## Homework Equations

1/((1/Zr)+(1/Zl))

I=V/R

## The Attempt at a Solution

First we simplify the voltage source into a current source

I=V/R

30<-90/15

=2<-90 A

to find the new current source we have I1+I2

=2<-90 A+4<90

=6<0A

Now to combine the resistor with the inductor

1/((1/Zr)+(1/Zl))

Therefore the new Z is
