Question
Nuclear fusion could provide humankind with limitless energy, making a gallon of seawater the energy equivalent of 300 gallons of gasoline. The National Ignition Facility (NIF) at Lawrence Livermore National Laboratory was designed for the "ignition" of nuclear fusion by bombarding a tiny deuterium-tritium pellet with energy from 192 converging laser beams. The NIF lasers deliver 2 MJ of energy in about 1 ns; The given figure shows the target chamber where the laser beams converge. The energy is stored in capacitors that, because of conversion inefficiencies, have to store some 400 MJ. (Note:NIF is more complicated than described here, and the numbers and technical descriptions are only approximate.)
If it were technically and economically feasible to double the voltage, how would the required capacitance change?
It seems like the answer should be 1/2, but according to this guy it's not... https://www.chegg.com/homework-help/questions-and-answers/nuclear-fusion-could-provide-humankind-limitless-energy-making-gallon-seawater-energy-equi-q10483035?trackid=1667d664&strackid=3813690f&ii=1
Just wanted a second opinion...
Explanation / Answer
Q = CV
If the voltage were to be doubled, the charge could get doubled as Q is proportional to V , keeping the capacitance constant.
Capacitance would remain the same
