 Electric charge is measured in terms of the coulomb (1 C), although this is a very large and not extremely practical unit of measurement.  For example, the charge in a bolt of lightning is about 15 C.  Express the charge in lightning bolt in

a.millicoulombs

b.kilocoulombs

\(Charge\ Lightning\ Bolt\\ Q_{lightning\ bolt}=15C\times\frac{1000mC}{1C}=\color{blue}15\ 000mC\\ Q_{lightning\ bolt}=15C\times\frac{1kC}{1000C}=\color{blue}0.015kC\)
