**Hints for 9/21 Assignment**

**Hint for 4.30**
The capacitive branch has an impedance of 1.1k - *j*6.1k or 6.2k \/ -80 deg.

The inductive branch has an impedance of 2.3k + *j*0.57k or 2.4k \/ 14 deg.

**Hint for 4.38**

The effective impedance is (4 + *j*4) ohm.

**Hint for 4.39**

The effective impedance is (0.6 + *j*0.9) ohm.

**Hint for 4.44**

The effective impedance of the capacitor in parallel with the resistor is (1 - *j*) ohm.
