#27 - Elementary Charge - smallest charge known to exist in nature
p +1.6 x
10-19 C
e- -1.6 x 10-19 C
Ex) Object has 4 p, 1 e-, charge?
+ 3 elem. charges or ...
+ 4.8 x 10-19 C
Ex) How many excess charges are
there in an object with a charge of
6 excess electrons
Ratio
1 elementary charge 1.6 X 10-19 coulombs
Divide by 1.6 × 10-19 C
-1.1 × 10-6 C (1.6 × 10-19 C)
c) 6.9 × 1012 electrons
b) 4.5 x 10-19 C
