A 15 resistor, an inductor with 8 inductive reactance, and a capacitor with 12 capacitive reactance are in parallel across an ac voltage source. The circuit impedance is-A-12.7 B-127 C-4,436 D-6,174 -A-12.7

Question

A 15  resistor, an inductor with 8  inductive reactance, and a capacitor with 12  capacitive reactance are in parallel across an ac voltage source. The circuit impedance is-A-12.7 B-127 C-4,436 D-6,174 -A-12.7

APTITUDE CRACK · Accepted Answer

The correct option is  A 12.7  Parallel : L &amp; C Z(lc) = 8i x ( 12i)/(8i 12i) = 24i Parallel : Z(lc) &amp; R Ztotal = 24i x 15 / (24i + 15) = 12.71, angle 32
