Take the capacitor in the other hand and touch the metal part of the screwdriver to both the terminals of the capacitor. You will see sparks and hear some crackling sound as an indication of electric discharge. Repeat a couple of time to make sure that the capacitor is completely discharge. Now, we will see a safe way to discharge the capacitor.
