Introduction to Capacitors, Capacitance and Charge
There are two types of electrical charge, a positive charge in the form of Protons and a negative charge in the form of Electrons. When a DC voltage is placed across a capacitor, the positive …
Why do both plates of a capacitor have the same charge?
How do we know that both plates of a capacitor have the same charge? You could argue conservation of charge, but I don''t see how conservation of charge implies the charge on both …
Why do both plates of a capacitor have the same charge?
There''s no reason the sides have to be equal, but if they aren''t, the capacitor obviously has a net electric charge. Moreover, the electric field lines emanating from the capacitor have to go …
