A capacitor of 2μF is connected in a radio circuit. The source frequency is 1000 Hz. If the current through the capacitor branch is 2 mA then the voltage across the capacitor is

The correct option is A 0.16Vi=VXCV=iXC =iωC =2×10−32π×1000×2×10−6 =0.16V

A capacitor of 2 $μ$ F is connected in a radio circuit. The source frequency is 1000 Hz. If the current through the capacitor branch is 2 mA then the voltage across the capacitor is

The correct option is A $0.16 V$
$i = \frac{V}{X_{C}}$
$V = i X_{C}$
$= \frac{i}{ω C}$
$= \frac{2 \times 10^{- 3}}{2 π \times 1000 \times 2 \times 10^{- 6}}$
$= 0.16 V$
