Answer:
The devises that sense the current flowing, tripping the circuitm and cutting off the electricity are the Ground Fault Circuit Interrupter (GFCI)
Step-by-step explanation:
The ground fault circuit interrupter is a mechanism hat cuts the flux of energy after sensing a disbalance to prevent a negative effect on the electronic devices that are connected to the interrupter. They are meant to stop the flux of current because a lot of accidents relate persons causing that electricity disbalance and suffering a very hard hit in their body.
