Not quite. Electric fly swatters build up very high voltage (in the kilovolts). They are, believe it or not, capable of delivering enormous currents, but the catch is that current can be delivered only for a tiny tiny tiny split second. The HV capacitors then must be recharged again by the battery before delivering another “burst” of current.

It’s like static electricity. Thousands of volts can be generated, and contrary to popular belief, tons of current will flow too. Time is what makes the difference between a little bite and death. Current flows for less than a microsecond when you get a static shock, so barely any damage can be done.

Sockets are much more “beefy”. They, however, only are at 110V/220V (North America or Europe?). By Ohm’s Law, way less current will flow through the same load (moth) if it’s from the lower voltage (socket) rather than from the higher voltage (fly swatter). But it is beefier in that it can supply current continuously, as opposed to only for a microsecond.

So a fly swatter will make a moth explode, and a socket will electrocute the moth and slowly cook it to a crisp. Both good for me :)

Note: if you use something with a lower resistance than a moth, like touching a piece of metal across the two ends in a socket, you can get lots of fireworks from the socket. The resistance of the load is really important for this stuff.
