Hi All,
I'm familiar with this analogy:
"The voltage is equivalent to the water pressure, the current is equivalent to the flow rate, and the resistance is like the pipe size." -HowStuffWorks.com
Power comes to our house on high-voltage, low current lines. Through a transformer, it gets converted to lower voltage, higher current. Neglecting losses, power is conserved.
If current is the rate of flow of electrons and my high-voltage lines are therefore carrying few electrons/sec (low current) ... how can I possibly get more electrons/sec (high current) after the transformer stage?
I know that the analogy is not perfect but am I thinking of it incorrectly? Please help ... it's bugging me so much ...
