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 20 ns; Fig. 23.17 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. (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?a. drop to one-quarter its original valueb. drop to one-half its original valuec. would not changed. would double
Step by Step Answer:
If the voltage across a capacitor is doubled the required c...View the full answer
