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

The statement is true because a wiggy, or a voltage tester, is generally designed to deliver a fixed output voltage, typically around 120 volts for testing circuits. This design means that the tool operates effectively without the need for adjusting the voltage range when measuring standard household voltages or similar applications. Wiggies are straightforward in function, making them user-friendly—users do not need to select different voltages to perform their tests, which simplifies the process, especially for basic checks.

In contrast, some other testing devices may require voltage range adjustments depending on the circuit being tested. However, with a wiggy, the design ensures consistency across its applications, allowing users to operate without concern for changing settings based on varying voltage levels. This characteristic is crucial for users who need to quickly assess electrical systems without additional steps.
