Question

The total impedance, Z, of an ac circuit containing components in series is equivalent to the sum of the individual impedances. Impedance is measured in ohms and is expressed as an imaginary number of the form Z=R+i*X. Here, R represents resistance and X represents reactance. 

If the impedance in one part of a series circuit is 7+3i ohms and the imedance of the remainder of the circuit is 3-4i ohms, find the total impedance of the circuit. 

What is the total resistance of the circuit?

What is the total reactance of the circuit?
