[04.04] Which best describes the current atomic theory?

True or false graphs must include scales that increase by the same amount

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e

Explain why electric current cannot exist if a current doesn't have a voltage source.
