+===== Example: Electric Potential from a Negatively Charged Balloon =====
 Suppose we have a negatively charged balloon with total charge $Q=-5.0\cdot 10^{-9} \text{ C}$. What is the electric potential (also called voltage) at a point $P$, which is a distance $R=20 \text{ m}$ from the center of the balloon?
@@ Line 12: / Line 13: @@
 We assume $P$ lies outside of the balloon. This is obvious, as $P$ is a distance $R=20 \text{ m}$ away from the center of the balloon.

-The electric potential infinitely far away from the balloon is $0 \text{ V}$. Read [184_notes:superposition#Superposition_of_Electric_Potential|here]] for why this is important.
