The extra electrons flow into the ground. Like in your radios. S* True. However, to be of any future use, they must be captured before this can happen. I'm keeping mine on a shelf in the back pantry. The first box is nearly full. |

You should use the Leyden jar. S* |

.. . 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* |

You and teachers live in the ideal world where are the ideal capacitors. I live in the real world and it is trivial to verify that the impedance of a capacitor is 1 / ( 2 X pi X f X C). As usual, you are totally confused. 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? Leakage and impedance are two separate things, idiot. |

What will be leakage in such case? S* So after you saying he lives in a world of ideal capacitors you now proclaim that a Leyden Jar is an ideal capacitor? Pot, kettle. Because it's not a real world "practical and useful in actual devices" capacitor, Leyden Jars inhale vacuum like almost nothing else in the capacitor universe. They are useless in virtually all practical applications. So Leyden Jars normally occupy the absolute bottom of the capacitor list. tom K0TAR |

S* I'll take that into account the next time I'm connecting a bleeder across a power supply output. Now that I know a capacitor will work ... |
