what is the value of current as well as voltage upto which
we will not feel shock and why?

Answer / ramesh
mainly it is voltage which cause the shock, but it always
associated with current no matter of magnitude.For ac
voltage 40v for dry skin and about for wet skin is harmful.

Answer / nithi
shock is mainly depending on the value of current flowing
through our body & also the condition of body(wet(or)dry).
If the current is above 5mA ,we will feel shock .so,shock
doesnot depend on the value of voltage(low voltage doesnot
mean low hazards).As i already said,shock is fully
depending our body condition.

Answer / arvind
Dear nithi,
if 5mA current is following that means it is a leakage
current and means voltage should be more and current should
be less it means voltage only giving the shock not the
current. and one more thing what u said is 5mA whether this
value is for single phase or three phase?

Based on CPI/CGPA they shortlist the candidates & than directly start Interview so there is no Written Exam or GD Only PI.Interview held @ MNNIT , ALLAHABAD On-Campus on 6th,Aug, 2007 & the Questions asked to me by Interview Board ( 4 People) are from HR/SummerTraining/BTP/Subject-core, POWER SYSTEM & MACHINE. time duration of I/V is about 15-20 Minutes. HR- Q.1 Name,hobbies & About family background ? Q2.What u know abt NTPC ?? Q3.Why u want to choose NTPC as ur Carrier's starting i.e power sector not any other Oragnisation or sector ?? Techincal Questions- Q1.What is the reason for transformer Noise ?? Q2.Which material is used for making Transformer oil & How u measure its dielectric strength & Name the test ? Q.3 Which Machine u will prefer 2 use if flammble gases are coming out at a place & why ?? Q4.What is relation b/w Transmission Lines & Communication Lines ? Q5.What is the maximum capacity Synchronus Machine & total powerGeneration in our country ? Q.6 In india Power generation is at 50Hz while in America its 60 hz ,why so ?? Advantage or disadvantage ?? Q.7 Maximum Generation Voltage in india ? Q8. What is the Voltage regulation & why its required n how much is permissible ? & causes of voltage variation ?? Q.9 Why electric shock is feel ?? n in a Electric Train why we didnt feel that ? Q.10 Have u seen/ experience of any power plant/ industry related to the power sector ? so these are the questions which not too diffcult i think was asked to me.
