HOLT Electricians Practice Exam

Which type of loads can alternating current general use snap switches control?

1. Only resistive loads

2. Resistive and inductive loads

3. Motor loads only

4. High voltage loads

The correct answer is: Resistive and inductive loads

The correct response is that alternating current general use snap switches can control both resistive and inductive loads. This versatility is crucial for electricians, as it allows for the operation of a wide range of devices. Resistive loads, such as incandescent light bulbs and electric heaters, draw current directly proportional to the voltage. Inductive loads, like motors and transformers, create a magnetic field that can affect the current flow in complex ways. Snap switches are designed to handle the inrush current typically associated with inductive loads while ensuring safe operation without overheating or failing. The functionality of these switches is particularly significant when managing home or industrial electrical systems, where different types of loads are frequently used. Thus, understanding that these switches can accommodate both resistive and inductive loads enables electricians to appropriately select and install wiring and switching components in diverse applications.
