Which capacitor condition would cause the circuit to stop conducting because current cannot pass through one plate?

Which capacitor condition would cause the circuit to stop conducting because current cannot pass through one plate?

• A. Open Capacitors
• B. Shorted Capacitors
• C. Fixed Capacitors
• D. Improperly Installed Capacitors

Answer: (A)

An open capacitor creates a break in the conducting path, so there is effectively infinite resistance between the circuit nodes and no current can pass. In a circuit, current needs a closed path; when the capacitor is open, that path is interrupted and the branch can’t conduct. The other conditions don’t inherently block conduction: a shorted capacitor would allow current to flow directly across the plates, while a fixed or improperly installed capacitor refers to non‑open states or mounting issues, not a broken path.
