There is no need to change voltage range on a wiggy. True or False?

The correct choice states that there is no need to change the voltage range on a wiggy, which is true. A wiggy, commonly referred to as a voltage tester, is designed to test circuits at a specific operational capacity without requiring adjustments to its voltage range. This characteristic makes it user-friendly and efficient for technicians working with various electrical systems.

When utilizing a wiggy, it operates according to its internal calibration suited for standard voltage levels found in electrical circuits. Since it is built to handle a range of voltages commonly encountered in residential and commercial wiring, users can perform tests without the complexity of switching voltage settings. This reliability and simplicity are particularly beneficial in fieldwork where quick assessments are necessary.

The other options suggest scenarios where changing the voltage range may be considered, but they do not apply to the standard use and functionality of a wiggy, which remains consistent across various testing situations.
