Chapter 5, Problem 10P

In the parallel RC circuit shown in Fig. P5.10. the total current I is the sum of the currents flowing through the resistor ( $I_R$ ) and the capacitor ( $I_C$ ). Assume $I_R=83.2\angle -33.7°mA$ and $I_{{}_C}=55.5\angle -56.3°mA$.

1. Write $I_R$, and $I_L$
2. in rectangular form.
3. Determine $I=I_R+I_L$
4. in both its rectangular and polar forms
5. Write the real and imaginary parts of $I$.
