Question

How much energy is stored in a 20 µF capacitor with a voltage rating of 15 volts?​

Answer 1

its a answer I hope it was helpful

Answer 2

Given:

capacitance(c) = 20×$10^{-6}F$

Voltage(v) = $15 volt$

To find:

Energy stored by the capacitor (Q)

Explanation:

The expression of the energy stored in the capacitor is

$Q=\dfrac{1}{2}CV^{2}$

Substitute value of C and V in the above equation

$Q=\dfrac{1}{2} (20\times10^{-6} )(15)$

$Q=15\times10^{-5}$ joule

Final answer:

Therefore, energy stored by the capacitor is $Q=15\times10^{-5}$ joule.
