# Is there any risk if we stand in between two large conducting plates (capacitor) connected to supply?

What are the risks involved if one were to stand between two large conducting plates (i.e area where air acts as the dielectric for these plates) and the capacitor is connected to a large voltage power supply in the following cases:

1. If the high voltage power supply is DC and applied for a long time and someone suddenly enters between the plates, is there any possibility of getting shocked in the transient state?

2. If the high voltage power supply is AC then what will be the effect at steady state if someone were standing in between the plates?

I thought that since the plates are electrically isolated due to air, if one were to stand in between the plates, they aren't going to get shocked although there is continuous current flowing through it (but it is due to the change in the electric field which causes induced electric current and the electrons of the air don't participate in current flow.)

I'm not sure whether I'm correct or not .

• If it's DC, the main concern is breakdown of the insulation between the two plates (arcing through air and the person), where the exact breakdown voltage depend on various factors. What sort of voltages are you working with, and what's an example of a scenario where this happens? // Just realized 2 is "AC" not "arc" Feb 27, 2021 at 7:35
• @syntax It is more of a theoretical question for knowledge purpose but what are the worst possible situations in both cases? Feb 27, 2021 at 7:41
• If you stand in between the plates, you change the air gap and provide a conducting path as has been explained in the first comment. Feb 27, 2021 at 8:16
• @Solar Mike but if I'm not physically touched the plates , how does I provide a conducting path? Feb 27, 2021 at 8:48
• Did you understand the words "you change the air gap"? Feb 27, 2021 at 8:49
