Which practice is recommended for capacitor discharge safety?

Discharging capacitors safely hinges on limiting the discharge current so you don’t get a shock or an arc. Using a resistor across the capacitor does this by converting the stored energy into heat in the resistor, pulling the voltage down gradually rather than creating a sudden short circuit. The insulated leads on the resistor setup keep your hands away from the live terminals and prevent accidental contact or bridging to other parts, which reduces the risk of electric shock or sparking. Shorting a capacitor with a tool creates a very large, uncontrolled current spike, which can cause sparks, damage components, or injure you. Handling a live capacitor is dangerous because the terminal voltage can remain high even if the circuit seems inactive. Letting it stay charged leaves a real risk of unexpected discharge. So the recommended practice matches this resistive discharge method with insulated leads, because it controls the energy release safely. After discharging, it's wise to verify zero volts with a meter before touching the capacitor.
