What is the function of a surge protection device?

• A. To enhance electrical flow to devices
• B. To protect electrical devices from voltage spikes
• C. To measure electrical current
• D. To convert AC to DC

Answer: (B)

The function of a surge protection device is to protect electrical devices from voltage spikes that can occur due to sudden changes in electrical current, such as those caused by lightning strikes, power outages, or fluctuations in the electrical grid. These voltage spikes can cause significant damage to sensitive electronic equipment, leading to failures or reduced longevity of devices. Surge protection devices work by diverting excess voltage away from the connected devices, thereby safeguarding their operation and ensuring that they continue to function correctly. This is particularly important for devices such as computers, televisions, and other electronics that are susceptible to damage from abrupt increases in voltage. The other choices pertain to different functionalities. Enhancing electrical flow is not the primary purpose of surge protection, as it could potentially allow harmful voltage spikes to affect devices. Measuring electrical current is a role for ammeters or similar devices, not surge protection. Converting AC to DC is a function of rectifiers, which is unrelated to surge protection. Thus, the primary role of a surge protection device is indeed to secure electrical devices from damaging voltage surges.
