high current

Answer / mu

if u touch 12V DC charger u won't fill any shock, however u
touch 230V & if you are grounded then u will get shock.

when u touch 11000V line to line with your body, it will
burn in seconds.

so the most important in KVA rating of any source to get
shocked, but voltage plays a vital role to become dangerous.

High current depends on load capability to drag it, if you
are touching any voltage with body & U r grounded then if
your resistance is more than VA rating of source then you
wont get shock.

Answer / amit goyal

High Current dangerous ,but high current only will flow and depend upon potential difference.

Answer / md. mosaddak kabir

Both are dangerous.High voltage damage our heart and when
high current passing through our body it will burns our body.

Answer / argha

we know V=IR ,i.e i=V/R
its clear that i proportional to V and vice verca .
so the main thing is the potential difference i.e v.
*human body can tolerate 5 mA current .more then that is the
causes death.
** the resistance if body is between 50-500 ohm.
so greater V causes Greater I .so both are dengarous.

Answer / algatz

both are dangerous....

Answer / krushna ch sahoo

High voltage bcos current depends upon
the voltage & resistance

Answer / shokenyu

Certainily High Voltage is dangerous

there are chanses that may survive a 230 v shock but u wont
survive at 22o KV.

Answer / 12354

Human body reacts to the current. The amount of damage will depend on the amount of current. However amount of current is directly proportional to the voltage. So high current is dangerous to human body bot it is caused due to high voltage or low body resistance(wet body condition)

Answer / satendra

It's High current . . . because of the I^2*R losses. And
these losses will occur in the outer skin and inner body.
While if i touch a 22kV line nothing will happen untill i
am not grounded.

what happen if generator exitation lost?

What is the need of earthing transformer for delta side of a transformer. (Think of a line section between a star/delta transformer at a grid substation and delta/star transformer at a village. An earthing transformer is there at the delta side of the star/delta transformer at grid substation). As there are no ground reference there will not be fault current if a one phase is grounded. Further L-L phase will be sensed by the primary side of star/delta transformer as a L-G fault. So why an earthing transformer is required at delta side
