When connecting electrolytic capacitors in series, what must be observed?

• A. The polarity marked on the component
• B. There is no polarity to observe
• C. Connect anode to anode
• D. Connect cathode to cathode

Answer: (A)

When connecting electrolytic capacitors in series, it is crucial to observe the polarity marked on the component. Electrolytic capacitors are designed with a specific positive (anode) and negative (cathode) terminal, and connecting them in reverse polarity can result in failure of the capacitor, which may include leakage, venting, or even explosion in some cases. In series connections, while the voltages across each capacitor can add up, each capacitor must be connected in a way that the positive terminal of one is connected to the negative terminal of the next for the series to function correctly, but the individual capacitor's polarity still needs to be respected. Therefore, failing to observe the correct polarity can lead to significant issues. In summary, the requirement to maintain the correct polarity is essential to ensure the reliability and safety of the circuit when using electrolytic capacitors in series, making it a fundamental consideration during assembly.
