True or False: A noncontact voltage detector can show the exact amount of voltage present.

A noncontact voltage detector is designed to identify the presence of voltage without making physical contact with the electrical system. It typically indicates whether voltage is present through visual or audible signals, such as lights or beeps, but it does not provide a specific voltage reading. The primary function of these devices is to enhance safety by alerting users to the presence of electrical energy, enabling them to exercise caution while working with or near electrical equipment.

Therefore, the statement that a noncontact voltage detector can show the exact amount of voltage present is false, as these devices are not capable of measuring or displaying precise voltage levels. Instead, they serve as a warning tool rather than a measurement tool.
