Probably you have to real study what is a capacitor, first. https://en.wikipedia.org/wiki/Capacitor#DC_circuits https://www.explainthatstuff.com/capacitors.html https://electronics.howstuffworks.com/capacitor.htm

( vs Conductors) So it depends on if it is in series or parallel.

DC doesn't flow very well through an essentially open circuit. As far as explaining it with equations, the current through a capacitor is: Ic = C * (dv/dt) No changing voltage means no current through the component.
