Small aircraft often have 24 V electrical systems rather thanthe 12 V systems in automobiles, even though the electrical powerrequirements are roughly the same in both applications. The explanationgiven by aircraft designers is that a 24 V system weighs lessthan a 12 V system because thinner wires can be used. Explain whythis is so.
