Question: 1 / 1030

When handling a high voltage capacitor in an electrical circuit, be sure it

Is connected to a power source

Has a resistor across its terminals

Is fully discharged before removing it from the circuit

When handling a high voltage capacitor in an electrical circuit, it is crucial to ensure that it is fully discharged before removing it from the circuit. This precaution is essential because capacitors can store electrical energy even after the power source has been disconnected, posing a significant risk of electrical shock if not discharged properly. By discharging the capacitor before removal, the stored energy is dissipated, reducing the risk of accidental shock or injury. Hence, option C is the correct choice in this scenario.

Options A, B, and D are incorrect because they do not address the primary safety concern associated with high voltage capacitors, which is ensuring they are fully discharged before handling or maintenance.
