Does This Homemade Electric Mousetrap Work?
This trap has some problems. For one, when the mouse touches the trap, the fur limits the the amount of current passed. Second, because this uses alternating current, every 120th of a second, the voltage drops to zero, which gives the mouse a chance to get away. Third, the initial shock is not lethal because most of the current doesn't pass through the heart. Moral of the story -- most modern electric mouse traps use direct current and an ever higher voltage to break down the resistance of the fur.
