What type of load can resistive and inductive alternating-current general-use snap switches control?

The option identifying that snap switches can control loads not exceeding ampere ratings is correct because these devices are designed to handle specific electrical load capacities. In practical terms, a snap switch has a defined ampere rating that indicates the maximum amount of current it can safely interrupt and sustain without overheating or failing.

When loads exceed the rated ampacity of the switch, it poses a risk of overheating and potentially causing a fire hazard. Snap switches are primarily utilized in common household circuits that predominantly handle resistive loads, like incandescent light bulbs or electric heaters, as well as inductive loads, such as motors and transformers, as long as these loads remain within the safe operational limits of the switch.

Understanding this helps ensure that electrical systems are installed safely and functionally, respecting the ratings of the components involved to prevent failure and maintain system integrity.
