What is the proper and safe method to discharge a capacitor?

• A. Using the positive and negative leads of an ammeter
• B. Using a capacitor discharging tool
• C. Connecting a screwdriver across the terminals
• D. Connecting a jumper wire across the terminals

Answer: (B)

The proper and safe method to discharge a capacitor involves using a capacitor discharging tool. This tool is specifically designed for the purpose of safely discharging capacitors without the risk of electric shock or damaging components. It typically features resistors that allow the stored energy to dissipate in a controlled manner, minimizing the potential for a sudden release of electrical energy which can be dangerous. While there are other methods mentioned, they do not guarantee the same level of safety. For instance, using a screwdriver can create a short circuit across the capacitor's terminals, which could result in a dangerous spark or even damage to the screwdriver and the capacitor. Similarly, connecting a jumper wire across the terminals can present a similar risk, as it might not adequately dissipate the stored energy while also posing a shock hazard. Employing an ammeter is also inappropriate because it is not designed for discharging capacitors and could potentially damage the meter or lead to inaccurate readings. Utilizing the proper discharging tool helps ensure safety and protects both the technician and the equipment involved.
