Question

The story energy of a capacitor is charged to 100 volt is 1 joule capacitance of a capacitor is

Answer 1

the ans is 0.02 F as energy is half cinto v square

Answer 2

Answer:

The energy stored of a capacitor charged 100 volts is a 1-joule capacitance of a capacitor is $C=200*10^{-6}F$

Explanation:

• A capacitor is used to store charge

• The electrical potential energy is stored in a capacitor

• For a capacitor with capacitance (C) and potential difference across the battery (V), the energy stored is

        $U=\frac{1}{2}CV^{2}$

From the question, we have

the energy stored in the capacitor is $U=1J$

the voltage across the battery $V=100v$

the capacitance of the capacitor   $C=\frac{2U}{V^{2} }$

put the values given

⇒  $C=\frac{2*1}{(100)^{2} }$

⇒$C=200*10^{-6}F$
