(1) There is a parallel connection circuit of resistor R and capacitor C. Next, coil L is connected in series to this circuit as shown in Figure 2. When the inductive reactance of the coil is X =oL, show the composite impedance of this circuit in complex numbers using XC and XL. (2) In the circuit of (1), when the deviation of the composite impedance is zero, the voltage and current are in-phase. Find R to satisfy the condition. (3) In (2), show the conditions that must be satisfied by XC and XL for R to exist. L jwL =jXL R E 1 1 jwc Xc
