What should be ensured after discharging a capacitor?

After discharging a capacitor, it is crucial to ensure that it is safe to handle. Capacitors can store a significant amount of electrical energy, and even after discharging, some residual voltage may remain. By confirming that the capacitor is safe to handle, you can prevent potential electrical shock or injury that could occur if there is still a charge present.

In practice, safety is paramount in electronics, as a charged capacitor can release its energy suddenly, which may lead to harmful situations. Therefore, ensuring its safety through proper discharging and verification is a vital step in handling capacitors.

The other options, while important in their own contexts, do not directly address the immediate concern of safety following capacitor discharge. Storing or disposing of a capacitor properly is essential, but only after confirming it is safe to handle. Testing for voltage is also a good practice, but it is secondary to the immediate concern of ensuring safety before physical interaction.
