What type of electrical accident can occur if a relay’s contacts become corroded?
A. Short circuit B. Open circuit C. Ground fault D. Overheating
Explanation: If a relay’s contacts become corroded, an open circuit can occur. This is because the corrosion may create a barrier that prevents the contacts from closing, meaning that current cannot flow through the circuit, potentially causing equipment failure.
