Application +4 | -1

A resistance of 40 ohm and an inductance of 95.5 millihenry are connected in series in a 50 cycles/second ac circuit. The impedance of this combination is very nearly

View answer and explanation

Correct option: C

50 ohm

Option C (50 ohm) is correct because the impedance is calculated using the formula

Z = \sqrt{R^2 + X_L^2}

circuit, potential difference across the capacitor may be greater than the applied voltage.

Reason (R) :

V_C=I X_C

, whereas
