Curious how it works?

The way it works is that the 4 AA batteries produce 6 volts which is then pumped up through a switching power supply and stored in a capacitor at a few hundred volts. If the capacitor is large enough there will be sufficient energy stored to kill any Mouse, Rat, Dog, Cat or Cow which happens to wander by.

It uses the same circuitry as a bug zapper

Thanks for all the answers! Now I have some terms I can search for to understand better.

well if u put the combined voltage of 4 of those batteries on your tongue, it would be a nasty shock, im guessing the skin of mouses is a stonger conductor of electricity than humans, plus its a tiny animal , so more easily harmed by electricity than humans, but the real electrical answer is high voltage capacitors inside the device, these have storage capacity of more than 1000s of volts inside them, if the mouse comes in contact, they will discharge 1 second of 1000 volts enough to kil the mouse.

A lot of strange answers.

It probably uses an oscillator and a transformer. The oscillator converts the 6 volts DC to a 6 volt P-P square wave, which drives a transformer, which converts the AC to a much higher voltage, at a lower current.

It may then rectify the higher voltage and store that high voltage DC on a capacitor, which discharges into the mouse.

if you search google for "electronic mouse trap schematic" you will see many different possibilities.

It contains a capacitor that stores the input voltage and releases a much higher voltage on activation. Same principle is used in camera flash guns and tasers.

Amperage kills

mice so small so it dont take much whenw e touch batterys it dont do nothin but when a moust touch battery they dead

whats known as a high voltage transformer .. transformers can be wound to increase 'or' decrease a voltage and it affects the amps to generally opposite the direction the voltage is adjusted ..

Use a trap that won’t cause the mouse to get hurt.
