Question
What is the importance/relevance to know the electric field distribution of a electrical apparatus? let's say a cable system or a circuit breaker?
Can electric field intensity effect these things ?
Hello Hemalan,
this depends on the strength of the field and the sensitivity of the elements inserted in the field. In general everything is influenced by electric field, but you need to consider the numbers and geometry in each individual case to see, whether or not to worry about it.
At home you will unlikely have high enough electric field or sensitive enough devices, certainly circuit breaker and cabling (except some special purpose cables) are fine.
In factories and laboratories however there are sometimes very intense fields and very sensitive equipment, so one needs to calculate the danger and take steps to prevent accidents and injuries.
Cheers,
Daniel

Questions anyone (teenager, undergrad, graduate, professional) may ask on physics, mathematics or inorganic chemistry. Questions may concern subjects themselves or a possible future career in them, if you need advice on a school or hobby project, or you just came across a question that is beyond your current curriculum. I answer bare textbook problems sometimes, but I reserve the the right to redirect you to Physics-Physics section. The kind of questions I like to answer: I just started having science classes at school and they seem difficult, but I enjoy them. Where do I find more information on this, which is not in textbooks but still comprehensible to me? Just leaving high school, and I feel science is really the thing for me. Can you recommend a school and an undergrad program suitable to my inclinations? I am in my second undergraduate year in Physics. We learned the basics of universe expanding this year, the Hubble constant and all that, but invited speakers that gave talks on astrophysics in our department seemed not to agree with this model at all. Is it of any use at all? I am building a [materials research] experimental device for my masters/doctorate thesis and I have the following problem:... I have tried ..., but it still doesn't work. Where might the problem be?
