Answer 1

The correct answer is option 2):(infinite)

Concept:

The reactance of the capacitor is given by

X_c = \(1 \over 2 \pi \times f \times C\)

where

f is the frequency in Hz

C is the capacitance in farad

Calculation:

Given

F3 Vinanti Engineering 03.01.23 D9

for a DC source f = 0

X_c = \(1 \over 2 \pi \times f \times C\)

= \(1 \over 2 \pi \times 0 \times 3\)

= \(\infty\)
