If one component in parallel circuit breaks, others still work?

If one component in parallel circuit breaks, others still work?

• A. They stop
• B. The circuit opens
• C. Other components work
• D. They burn out

Answer: (C)

In a parallel circuit, each component has its own path across the same two nodes, so current can flow through the other branches even if one path breaks. If one component fails or its branch opens, that branch simply stops drawing current, but the remaining branches still have the full source voltage across them and continue to operate. That’s why other components keep working when one branch breaks. This contrasts with a series arrangement, where a break stops the entire circuit.
