Which circuit component is crucial for protecting against voltage spikes?

• A. Resistor
• B. Diode
• C. Surge protector
• D. Capacitor

Answer: (C)

The surge protector is specifically designed to safeguard electrical equipment from voltage spikes, which can occur for a variety of reasons, such as lightning strikes or sudden changes in electricity usage within the circuit. Surge protectors work by diverting or absorbing excess voltage, ensuring that the connected devices are not subjected to damaging levels of electricity. In contrast, while resistors limit the flow of current, they do not provide protection against voltage spikes. Diodes can allow current to flow in one direction and can help manage specific conditions, but they are not primarily intended for spike protection. Capacitors store electrical energy and can filter out voltage fluctuations, but they do not inherently protect against high voltage surges. Therefore, the surge protector is the most appropriate component for addressing the specific challenge of voltage spikes.
