Why does the distance between the plates of a …
If the capacitor is charged to a certain voltage the two plates hold charge carriers of opposite charge. Opposite charges attract each other, creating an electric field, and the attraction is stronger the …
Notes: What is Capacitance?
Understanding Capacitance Notes: If a second metallic plate is moved close to the charged plate the field is intensified and mostly confined to the area between the plates – hence the geometry of the Leyden jar and most other capacitors. This potential energy can
