dear friends.. i am class 12 cbse students
we are supposed to do an investigatory project on resistance and resistivity
the project has been completed ...
but we need to have around 10 - 12 pages on relevant information on resistance..i wud be grateful if u cud hel p me collecting some information by advising some sites or so
thank you

Physics news on Phys.org
www.howstuffworks.com , you can get good examples of commonly used technology that uses resistance to operate.
 
thanks a lot nenad .. .please advise me wid more links if u come across
thank you

Assume that this is a case where by sheer coincidence, two sources of coherent single-frequency EM wave pulses with equal duration are both fired in opposing directions, with both carrying the same frequency and amplitude and orientation. These two waves meet head-on while moving in opposing directions, and their phases are precisely offset by 180 degrees so that each trough of one wave meets with the crest of the other. This should be true for both the electric and magnetic components of...
