Understanding Electrical Wiring Basics

What is the purpose of the ground wire in an electrical circuit?

• To carry the electrical current to the appliance

• To provide a path for electrical current to safely return to the ground in case of a fault

• To supply power to the circuit

• To act as a backup for the neutral wire

Which wire is typically connected to the brass-colored screw on a receptacle?

• Ground wire

• Hot wire

• None of the above

When stripping electrical wire, approximately how much insulation should be removed to create a hook?

• 1 inch

• 1/2 inch

• 2 inches

• 1/4 inch

What color is typically associated with the neutral wire in household wiring?

• Black

• Red

• White

• Green

Which of the following is NOT a basic component of an electrical circuit?
