How can arc suppression be achieved in AC applications?

Explanation:
Arc suppression in AC applications is effectively achieved through techniques such as snubber circuits and proper circuit design. Snubber circuits are specifically designed to mitigate the effects of transients and voltage spikes that can occur due to switching operations. They typically consist of a resistor and capacitor network that absorbs the energy of the arc, thereby preventing it from sustaining and causing damage to other components in the circuit. Proper circuit design also plays a crucial role in arc suppression. This includes considerations such as selecting appropriate materials, using adequate ratings for components, and implementing protective devices that can interrupt current flow quickly in the event of an arc. These strategies collectively help to manage the energy that contributes to an arc and ensure safe operation in AC systems. In contrast, eliminating all circuit breakers would not prevent arcs; instead, circuit breakers provide protection by interrupting the circuit during fault conditions. Increasing the voltage supplied to the circuit could potentially escalate the severity of arcs. Finally, while using only resistive loads can reduce some transient behavior, it does not fully address the underlying causes of arcing associated with switching inductive or capacitive loads.
