What is the purpose of a surge protector?

• A. To increase electrical load capacity
• B. To protect electrical devices from voltage spikes
• C. To regulate voltage levels in a circuit
• D. To reduce current flow in a circuit

Answer: (B)

The primary purpose of a surge protector is to shield electrical devices from voltage spikes or surges. These voltage spikes can occur due to various reasons, such as lightning strikes, power outages, or fluctuations in the power grid. When excessive voltage enters a circuit, it can potentially damage sensitive electronic devices, leading to costly repairs or replacements. A surge protector detects these spikes and diverts the excess voltage away from the connected devices, ensuring they remain safe and function properly. This protective mechanism is crucial for maintaining the longevity and reliability of electronic equipment.
