What is the difference between earthing and grounding?
The key difference between earthing and grounding is that the term “Earthing” means that the circuit is physically connected to the ground which is Zero Volt Potential to the Ground (Earth). Whereas in “Grounding” the circuit is not physically connected to ground, but its potential is zero with respect to other points.

Does a house need a ground wire?

They are usually copper plated steel with a connector called an acorn at the top to hold the ground wire to the rod.
Does every house have a grounding rod?

How do you tell if your house is not grounded?
Look at the outlets in your home. The first sign of proper grounding is whether you have two-prong outlets or three. A three-prong outlet has a narrow slot, a larger slot and a “U-shaped slot.” The U-shaped slot is the grounding component.
