3. In a lightning bolt, it is estimated that a charge of -20 C is transferred from a cloud to the Earth. How many electrons make up such a lightning bolt? N = Q/e N = -20c / 1.6 x 10^-19 N = -1.25x10^20 I'm pretty sure this is the right answer. What I'm wondering is... how can I have a negative number of electrons? This makes this formula seem flawed to me. I guess I can just remove the negative sign after the fact, is that what most people do?
