A 15 \(\mu F\) capacitor is connected to a 240V, 50Hz ac. source. Calculate the reactance of the capacitance [\(\pi = 3.142\)]

A.

16\(\Omega\)

B.

68\(\Omega\)

C.

106\(\Omega\)

D.

212\(\Omega\)

View answer & explanation

Correct answer is D

\(X_c = \frac{1}{2 \pi fc}\)

= 2 x 3.142 x 50 x 15 x 10-6

= 212.179\(\Omega\)
