The Deep Dive
When you connect two charged spheres with a wire, charge will flow from one sphere to the other until they reach the same electric potential. The potential
of each charged sphere can be calculated using the formula
, where
is Coulomb’s constant,
is the charge, and
is the radius of the sphere.
For the first sphere,
and for the second sphere,
. After simplifying, you will find that both spheres will ultimately stabilize at the same potential, leading to a transfer of charge until equilibrium is reached.
Upon performing the specific calculations, you’ll find that a net charge will flow from the sphere with the higher charge density (smaller radius) to the larger radius sphere until their potentials equalize, setting the stage for fun electrostatics!
Remembering to double-check calculations for errors can save you from common mistakes in understanding potential differences and charge distribution!
