  1. Feb 22, 2010 #1
    1. The problem statement, all variables and given/known data

    A strong lightning bolt transfers about 24 C
    to Earth.
    How many electrons are transferred? The
    charge on an electron is −1.60218 × 10−19 C.

    2. Relevant equations


    3. The attempt at a solution

    i wasnt sure which charge to use. i pluged in the #s given plus the elementary charge using -, since its an electron. then i tried adding it and a couple of other things.... i got confused! thx!!!!

    with these types of questions, they usually ask whether the particle has a defecit/ excess of electrons, usually if the charge is positive that means that it has a defecit of electrons, likewise if the charge is negative, there are an excess amount of electrons
