The flash of a nearby lightning bolt followed by the crack of thunder can’t help but make you take notice of the power of nature. And it’s a good thing you get that reminder because lightning kills more people than floods, hurricanes or tornadoes. Some of those deaths are from direct strikes, but most are from the distributed effects of the large surge of current created when lightning hits. That current can make its way through electrical wires into your home, damage your appliances and put you at risk — your television set is not immune to the danger.
