Question:

What is the energy stored in the 15.5 {eq}\mu {/eq}F capacitor of a heart defibrillator charged to 8.25*10^3 V?

Find the amount of charge stored on the capacitor

: Energy stored in a capacitor.

A capacitor gets charged if a battery is connected to it. It is a device which stores energy

The energy stored in a capacitor is expressed by the relation

{eq}U=\frac{Q^{2}}{2C}=\frac{1}{2}QV=\frac{1}{2}CV^{2} {/eq}

  • C=capacitance
  • Q=charge
  • V=potential

Answer and Explanation:

Given:

{eq}*U=15.5 \mu F *V=8.25\times10^{3} \ V {/eq}

Applying the formula

{eq}\begin{align} &U=\frac{1}{2}CV^{2}\\ &=\frac{1}{2}(15.5\times10^...
