New Energy Sources WhatsAppI''m a bit confused about capacitors. I understand they store energy in a field by accumulating opposite charges on the different plates. So a 1 farad capacitor will store 1 coulomb of charge if subjected to 1 volt if I understand the math right. 1 coulomb is also 1 amp-second, so this capacitor can supply 1 amp of current for 1 second.
New Energy Sources WhatsAppIt is worth noting that both capacitors and inductors store energy, in their electric and magnetic fields, respectively.
