# Capacitors for high current systems?

Why area capacitors considered ideal for systems that require excessively high current(in the magnitude $10^6$) for short pulses? Also, how can they manage to output high current in that range without causing severe damage? High current at that magnitude would lead to massive heat. I can't imagine the system to function more that a few ms, is a second or more even possible?!

How can they manage the capacitors energy storing capacity & how they are connected(series/parallel), with respect to the resistance of all the wires & terminals connecting everything, Incredible systems.

• You said it yourself: "short pulses". You can consume a large amount of power for a short time and only cause a temperature increase proportional to $Pt$. – The Photon Oct 29 '16 at 15:49

A one second pulse of $10^6$ amps through a resistance of 0.01 ohms would dissipate $10^{10}$ joules of energy. That is equivalent to about 2.4 tons of TNT. A one ms pulse in the same resistance would dissipate $10^7$ joules of energy. That is equivalent to about 10 sticks of dynamite.
