A huge 4.0-F capacitor has enough stored energy to heat 2.5 kg of water from 21 degree Celsius to 95 degree Celsius. What is the potential difference across the plates?(adsbygoogle = window.adsbygoogle || []).push({});

What equation am I supposed to use for potential difference?

Is it V = Change in PE / q

V= - W / q

V = (PE)(.5)/ Q

Also, I'm supposed to find how much energy is required to heat the water right? What equation do I use for that?

I'm just confused with this problem... Can somebody please help. Thanks
