At a gas pressure of 0.2–0.4 Pa, the fraction of ions sputtering the target (δ = …
How do capacitors work?
Artwork: A dielectric increases the capacitance of a capacitor by reducing the electric field between its plates, so reducing the potential (voltage) of each plate. That means you can store more charge on the plates at the same voltage. The electric field in this capacitor runs from the positive plate on the left to the negative plate on the right.
