In case of a van de Graaff generator, the breakdown field of air is.
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
In a Van de Graaff generator, which is used to generate high voltages, the breakdown field of air plays a crucial role in its operation.
Step 1: The breakdown field is the electric field strength at which the air becomes conductive and allows current to flow. This typically occurs when the electric field strength exceeds approximately 3 million volts per meter (3 MV/m).
Step 2: The diagrams provided likely represent different aspects or values of electric field strengths, but the correct answer must pertain to the standard breakdown field value for air.
Based on this understanding, the most likely correct option is A.
