Hi guys,
I am a physics graduate, currently working in an experimental lab. Before coming here, I have no solid experience in lab stuffs. Anyway I enjoy working at lab a lot.
The first task I have is to learn and master a programable DC source (Yokogawa 7651). To do this, I personaly think that I need some knowlegde for the following:
1) What are the typical values of voltage, current, resistance of a circuit? I would like to know the typical values of them ranging from as small as table circuits to industrial circuits.
2) How dangerous is a value of voltage, or current? I think we can calculate the power consumed by the whole circuit by a simple estimate P=VI=V2/R=I2R. However, this is for the whole circuit, rather than for a small object such as our body when coming into contact with the circuit. Make it precise, is there anyway to calculate the power that our body will be receiving from a circuit, given some necessary information?
I would appreciate if you guys like to share with me you says or some links that answer to the above doubts.
Thanks,
Xian Yang
