Question

A capacitor is used to store 24 Wh of energy at 1200 V. What should be the capacitance of the capacitor? (A)  120 mF  (B)  120 μ F  (C)  24 μ F  (D)  24 mF

U=(1/2)CV2 ⇒ 24× 3600=(1/2)× C× (1200)2 ⇒ C=120 mF

Q. A capacitor is used to store 24 Wh of energy at 1200 V. What should be the capacitance of the capacitor?

$120 m F$

$120 μ F$

$24 μ F$

$24 m F$

$12 μ F$

$U = \frac{1}{2} C V^{2}$
$\Rightarrow$ $24 \times 3600 = \frac{1}{2} \times C \times (1200)^{2}$
$\Rightarrow$ $C = 120 m F$
