Answer:B
What type of electrical accident can occur if a relay’s coil burns out?
A. Short circuit B. Open circuit C. Ground fault D. Overheating
Explanation: If a relay’s coil burns out, an open circuit can occur. This is because the coil is no longer able to generate a magnetic field, which means the relay’s contacts will not be able to close and allow current to flow through the circuit, potentially causing equipment failure.
