Question

If resistance of 100 W and inductance of 0.5 henry and capacitance of 10 × 10⁶ farad are connected in series through 50 Hz A.C. supply, then impedance is -

• A. 1.8765 W
• B. 18.76 W
• C. 187.6 W
• D. 101.3 W

Answer 1

Answer: (C)

187.6 W

Answer 2

R = 100 W

X_L = 2pfL

X_C = $\frac{1}{2\pi fC}$

Z = $\sqrt{R^{2} + (X_{L} - X_{C})^{2}}$
