16. Express the following complex numbers in rectangular form: (a) 50/-75; (b) 19e30: 2.5-30 +0.5/45. Convert the following to polar form: (c) (2+ j2)(2 j2); (d) (2 + j2)(5/22). PRNA 20. Perform the indicated operations, and express the answer in both rectangular and polar forms: 2+ j3 10/25 5/-10 3/15 +. 3-j5 (a) 1+8/90 -4; (b) j2: (1- )(1+ j) + 1/0* (c) (3/-90) + 5/-45 determine I. 24. Employ a suitable complex source to determine the steady-state current i in the circuit of Fig. 10.52. 5 sin (351 - 10) V 0.01 F 0.4 H I FIGURE 10.52
