Q. If a dog rolled around on a carpet as well as gets statically and a flea jumps on it will the flea get electrocuted?

Answer:-

It will but possibly not and such experiment would be interesting one. Electrostatic electricity has a big prospective - thousands volts - but small power when it gets discharged that meaning the potential will subsides momentarily to null volts with the current caused extremely negligible. This current will make little harm to the flea which as well consists of very resistive substance. The current might bang over the insect but won't kill it I believe.
