High Voltage AC and DC

[skellyeo03]

Can someone explain to me exactly why high voltage is classed as 1000 for AC and 1500 for DC?

To do with how far the electricity will arc in a nutshell.

Edit: miss understood the question as to why the values were different. The above is why this level was chosen.

The AC voltage is RMS, if you convert to peak it will be close to the DC value.

 

[Bobster]

^^ this is also true, off the top of my head, is around 1400v peak.

 

[telectrix]

is that root 2 in decimal? 1000 x 1.414. where does x10 come in?

 

[Bobster]

Vrms = 0.707 * Vmax

 

[telectrix]

or Vmax = rms div. by 0.707

 

[telectrix]

but that's peak V, not peak-peak for that it's x2, (no 10's in hrere)

 

[Bobster]

Vrms = 0.3535 * Vpp

Or

Vpp = Vrms/0.3535

 

[telectrix]

Vrms = 0.3535 * Vpp

Or

Vpp = Vrms/0.3535

Does this vary depending on the type of nutshell? Would it arc further in a walnut compared to a peanut?
