Question

As Rhonda plugs her device back in, she notices that it has a three-prong plug. She is reassured by this because three-prong plugs have _____ two-prong plugs, and are therefore safer.

a) More grounding capability than
b) Less grounding capability than
c) Fewer electrical contacts than
d) Greater resistance than

Answer 1

Three-prong plugs have more grounding capability than two-prong plugs, making them safer.

Step-by-step explanation:

Three-prong plugs have more grounding capability than two-prong plugs, making them safer.

The third prong on a three-prong plug is called the earth/ground wire. It provides an alternate pathway for electric current to flow into the ground in case of a fault. This helps prevent electrical shocks and reduces the risk of electrical fires.

In contrast, two-prong plugs lack an earth/ground wire, which makes them less effective at providing protection against electrical hazards.
