The correct Answer is:
To solve the question regarding the dielectric strength of vacuum, we will follow these steps: ### Step-by-Step Solution: 1. **Understand the Concept of Dielectric Strength**: - Dielectric strength is defined as the maximum voltage that an insulating material can withstand without breaking down and allowing the flow of electric charge. 2. **Identify the Properties of Vacuum**: - Vacuum is considered a perfect insulator. This means that it does not allow any electric current to flow through it under normal conditions. 3. **Determine the Dielectric Strength of Vacuum**: - Since vacuum is a perfect insulator, it requires an infinitely high voltage to break down its insulating properties. Thus, the dielectric strength of vacuum is theoretically infinite. 4. **Select the Correct Answer**: - Based on the understanding that vacuum has infinite dielectric strength, we conclude that the answer to the question is "infinity". ### Final Answer: The dielectric strength of vacuum is infinite. ---
