.. . A box is not the best condenser. You should use the Leyden jar. S* How about a nice modern compact capacitor? Regards, Ian. |

Who wants to try to explain to this babbling idiot that the impedance of a capacitor is 1 / ( 2 X pi X f X C) which means if f is zero (DC) the impedance is infinite and there is no conduction (in an ideal capacitor). |

You and teachers live in the ideal world where are the ideal capacitors. Leyden jar has insulator made of glass. It is possible to make it with insulator "made" of the air. What will be leakage in such case? S* |

If it helps you, capacitors pass AC and block DC. Each insulator is a weak conductor. At DC and pulse current electrons are flowing through the insulator (leakage). At AC not. At AC the charging/discharging take place. The electrons flow into plate and come back. Charging current and discharging current do not pass or by-pas the capacitors. S* |

S* I have a special oil extracted from the fat cells of rattlesnakes that cures all cancers. Please send check for $500 for one pint. This oil also provides artificial earth ground for all antennas.
