AC Circuits

Question

A circuit has a resistance of $11 Ω,$ an inductive reactance of $25 Ω$ and a capacitive resistance of $18 Ω .$ It is connected to an ac source of 260 V and 50 Hz. The current through the circuit (in amperes) is

Moderate

A

11
B

15
C

18
D

20

Solution

$Z = \sqrt{R^{2} + {(X_{L} - X_{C})}^{2}} = \sqrt{{(11)}^{2} + {(25 - 18)}^{2}} = 13 Ω$
Current $i = \frac{260}{13} = 20 A$
