• Short-circuiting

• Grounding

What does earthing provide to the leakage current?

• A complex path

• A simple path

• A high resistance path

• A short path

What happens to the short-circuit current of the equipment during earthing?

• It passes to the earth

• It remains in the equipment

• It gets amplified

• It gets stored

What is the potential of the earth in the context of earthing?

• High potential

• Low potential
