Before touching a small capacitor connected to a de-energized circuit, or even one that is completely disconnected, you should do what FIRST?

Agently tap the body with a screwdriver
Bshort circuit the terminals to make sure that the capacitor is discharged
Ctag it with a de-energized tag
Dbe equipped with an insulated fuse puller
AI Explanation

The correct answer is B) short circuit the terminals to make sure that the capacitor is discharged. Before touching a small capacitor, it is essential to ensure that the capacitor is fully discharged. Capacitors can store a significant amount of electrical charge, even when the circuit is de-energized or disconnected. Shorting the terminals of the capacitor ensures that any residual charge is safely dissipated, preventing the risk of electric shock or damage to the capacitor or other components. The other options are not the correct approach. Tapping the body with a screwdriver (A) does not reliably discharge the capacitor. Tagging it as de-energized (C) does not actually discharge the capacitor. Using an insulated fuse puller (D) is unnecessary if the capacitor is properly discharged.
