Under what conditions will the strength of current be the same for connection in series and in parallel for n cells.
# A wire of resistance R is stretched so that its radius decreases by factor n. Calculate its new resistance.
#Why are the resistance coils made of Constantine and mangnin and double wound on non conducting frame????
#Give 2 reasons why potentiometer is preferred is preferred over voltmeter for measuring E.M.F...
and please see and answer try to answer all questions wholly...
thnx
