Each capacitor generally consists of two conductors separated by a non-conductive region, however a great changed happened in the modern capacitors but the principle has been remained the same as the first day designed. In this paper was attempted to show novel capacitor which one of the conductors was coated and covered with dielectric and sunk into another conductive liquid which supposed as conductor and it is mercury because of two important features, the first being conductive and second the liquidity. In this paper experimented by the lacquer coated wire and the aluminum plate submerged into mercury then in experiments mercury charged and discharged, as a result it was working as a capacitor. The experiments was done by following sets: a DC power supply (DF1730 SB5A), multimeter, an LC meter (A6243- HONEYTEK).the experiment results showed that mercury could appropriately substitute by one of two conductors in capacitors. In addition, the simulation will have higher capacity till one farad and more.
