Method and steps

Use complex numbers to solve a parallel arrangement of impedances giving the answer in both Cartesian and polar form a) Two impedances, Z1 = (3+ j6 ) and Z2 = (4 -j3) are connected in parallel to a supply voltage of 120 V. Determine the magnitude of the current and its phase angle relative to the voltage both in polar form and Cartesian form.
