When an incandescent lightbulb is turned on, about 0.50 C of charge moves through the filament each second. How many electrons are flowing through the filament?
1 electron has a charge of 1.602176565×10−19 C so 1 C represents 1019/1.602176565 electrons
0.5 C represents 0.5*1019/1.602176565 electrons
0.5×10(19)1.602176565=3120754671630089658.6887725448661771
or approximately 3*1018 electrons.
