What are the differences between an AFCI outlet and a GFCI outlet, and how do they provide electrical safety in a residential setting?

An AFCI outlet protects against electrical fires caused by arcing, while a GFCI outlet prevents electric shock from ground faults. AFCI outlets detect dangerous arcing in the wiring, while GFCI outlets quickly shut off power if there is a ground fault. Both outlets enhance electrical safety in homes by reducing the risk of fires and shocks, respectively.
