medium

$5.0\, \mu F$ કેપેસિટરને $800\, V$ સુધી ચાર્જ કરીને વાહક સાથે જોડતા ડિસ્ચાર્જ દરમિયાન વાહકને આપેલ ઊર્જા .....

A

$1.6 \times 10^{-2}$

B

$3.2$

C

$1.6$

D

$4.2$

Solution

The energy of conductor during discharge is calculated as,

$U=\frac{1}{2} C V^{2}$

$=\frac{1}{2}(5.0 \mu F )(800 V )^{2}$

$=\frac{1}{2}\left(5.0 \mu F \times \frac{1 F }{10^{6} \mu F }\right)(800 V )^{2}$

$=1.6$ Joule
