What is the electric potential difference for two spheres capacitors connected in series [closed]
Consider two spherical capacitors with Identical radii for the inner and outer spheres (let them be a and b). +q and -q charges are in the inner and outer sphere on Both the capacitors. Now I connect ...

Problem understanding the use of differentials in equation for energy stored in a capacitor
I was going through the Feynman Lecures on Physics Vol. II and arrived at section 8.1, where the equation for the energy stored in a capacitor is obtained.
We consider now the energy required to ...

Effects of Dielectric on the Electrostatic Potential Inside a Capacitor
Let's consider two identical capacitors (same geometry) with the same applied DC voltage, but with different dielectrics.
Is the electrostatic potential function V (y) (with y = distance with ...

Why, intuitively, does a capacitor create current?
Suppose we have a planar capacitor connected to a closed wire. If the capacitor is charged, we know that the stored energy will be dumped in the form of current, electrons flowing from the negative ...

How can I theoretically describe the potential between two capacitors in series?
Suppose to have two capacitors in series:
The voltage in the middle point will be:
$$
V_X = V_1 \frac{C_1}{C_1+C_2}
$$
How can this be explained? It's been asked in electronics, and explained in ...
