Exercise 19 Page 217

Combine the real and imaginary parts.

7-j ohms

Practice makes perfect

To find the total impedance we add the two given complex numbers.

(3+2j)+(4-3j)

Remove parentheses

3+2j+4-3j

CommutativePropAdd

Commutative Property of Addition

(3+4)+(2j-3j)

Factor out j

(3+4)+(2-3)j

Add and subtract terms

7-j

The total impedance in the circuit is 7-j ohms.
