Brak—

If you think of a circuit as a tube and the electrons as marbles... the amperage is how many marbles pass a given point in a given amount of time... the voltage is how steeply tilted the tube is... 250 volts would be a tube that is at a 80˚ angle from horizontal and the marbles move pretty quickly... 12 VDC would be the same tube at a 20˚ angle from horizontal... the marbles still move, but not as quickly...

If you cut a section out of the tube... that would be a blown fuse. The higher the voltage, the more likely the marbles are to jump the gap. At 20˚ from horizontal a small gap would probably drop any marbles trying to cross. At 80˚ the gap probably has to be a bit larger for the marbles not to jump it.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
