Question

hA $5 \mu \mathrm {~F}$capacitor is connected to a 200 V, 100 Hz ac source. The capacitive reactance is

• A. 212$\Omega$
• B. 312$\Omega$
• C. 318$\Omega$
• D. 412$\Omega$

Answer 1

Answer: (C)

318$\Omega$

Answer 2

: Here, ,

The

capacitive reactance is ,

$\therefore \mathrm { X } _ { \mathrm { C } } = \frac { 1 } { 2 \times 3.14 \times 100 \times 5 \times 10 ^ { - 6 } }$

$= 3.18 \times 10 ^ { 2 } \Omega$

$= 318 \Omega$
