  A related question: Why do we get an electric shock fom a hot wire(phase) even though we are wearing slippers as an practical case we can see the the movie 3idiots where in both of the scenes the actors are wearing slippers and still receive shock!

  wearing slippers will not prevent shocks....i have got hit from serious shocks when am in lab wearing shoes,apron etc etc...which help in resisting the magnitude of the shock....

  guys stray capacitance occurs at high voltages see at 11KV to 400KV or higher voltages stray capacitance comes to picture so we need clearance for that even we dont touch lines we get shock if we have no clearance between wire and us
  so there exits stray capacitance due to high potential difference between wire capacitance
  so we should not stand nearer to such high voltage lines
  for more details refer to high voltage engineering by wadwa

  guys....is it true that standing below the power line is dangerous??people say that due to stray capacitance,we act like a capacitor...it aint a joke right??😐

  hey i didn't noticed this that will be because of ground capacitance i think not because of stray capacitance

  most of my friends too said that holding an umbrella below the power line.....or anything that makes the distance between the person and the line shorter can make us act like a capacitor...

  yes thats right that capacitance is called as ground capacitance

  yes thats right that capacitance is called as ground capacitance

  so is it harmful??

  definitely
  i have a live example a worker working in our college unknowingly moved under 11KV line while working on roof
  he got shock and died
  thats the power
  he is not even touched the line note this point

  oh... k thanx

  and is there a difference between ground capacitance and stray capacitance?? :S
• 

  narayana murthy

  yes ground capacitance is with reference to ground and stray is between capacitors

  its simple parth
  when a magnetic field and current is at 90deg difference then force will be exists here at another 90deg
  like flemings left hand rule
  here force will be done as a angular speed
