The correct answer is: E. None of the above
A wrist grounding strap is a safety device that helps to protect workers from electrical shock. It consists of a strap that is worn around the wrist, a conductive cord that connects the strap to a grounding electrode, and a grounding electrode itself. The strap and cord are made of conductive materials, such as metal, that allow electricity to flow through them. The grounding electrode is a conductor that is buried in the ground and provides a path for electricity to flow away from the worker.
When a worker is using an electrical tool or equipment, there is a risk of the tool or equipment becoming energized. If the worker comes into contact with the energized tool or equipment, the electricity will flow through the worker’s body and could cause serious injury or death. The wrist grounding strap helps to prevent this by providing a safe path for the electricity to flow away from the worker. The strap and cord conduct the electricity away from the worker and to the grounding electrode, where it is safely dissipated into the ground.
A surge protector is a device that is designed to protect electrical equipment from damage caused by power surges. A capacitor is an electrical device that stores energy in an electric field. A voltmeter is an instrument that measures voltage. A resistor is an electrical device that resists the flow of electricity.
None of these devices are necessary for the proper function of a wrist grounding strap.
