What is the full form of MCB? Which one of the following has two fuses? A fuse works as a safeguard for a circuit. A fuse wire is an alloy of tin and copper. It disconnects the electric circuit when current overflows in it.
Understand the Problem
The question is asking for the full form of 'MCB' and also presents a statement regarding the function of a fuse in a circuit, along with arguments about the correctness of certain statements related to it. This requires knowledge of electrical components and their functions.
Answer
MCB: Miniature Circuit Breaker. Power circuit has two fuses. Statement is correct; second argument is correct.
The full form of MCB is Miniature Circuit Breaker. A power circuit typically has two fuses. The statement is correct, but only the second argument is correct.
Answer for screen readers
The full form of MCB is Miniature Circuit Breaker. A power circuit typically has two fuses. The statement is correct, but only the second argument is correct.
More Information
MCBs are preferred over traditional fuses because they can be reset without needing replacement. A power circuit often has two fuses to protect different parts of the system.
Tips
Confusion might arise with the materials used in fuse wires; they often are made of lead and tin, not tin and copper.
