Why are household wall sockets alternating current (AC) instead of direct current (DC)? Select all that apply.

Why are household wall sockets alternating current (AC) instead of direct current (DC)? Select all that apply.


AC is typically safer than DC.


AC is typically more stable than DC.


Power loss in transmission is minimized with low current.


It is easier to scale the voltage of AC from low-to-high and high-to-low than with DC.

Answer 1

It is easier to scale the voltage of AC from high to low and low to high than with DC

Step-by-step explanation:

typically power is used far away from the place where it's generated so to ensure that transmission losses( copper losses) are minimized voltage has to be stepped up during transmission..but due to the fact that most house hold equipment requires low voltage levels it has to be stepped down once it reaches a household/ domestic load...it's easier to do this for Ac than for DC.
