What type of electrical accident can occur if a relay is used to switch high voltage or high current loads?
A. Short circuit B. Open circuit C. Ground fault D. Overheating
Explanation: If a relay is used to switch high voltage or high current loads, overheating can occur. This is because the relay’s contacts may not be able to handle the high current or voltage, and can become damaged or melt, potentially causing equipment failure or starting a fire.
