Questions
A wire of resistance R is divided in 10 equal parts. These parts are connected in parallel. The equivalent resistance of such connection will be
detailed solution
Correct option is A
Each part will have a resistance r = R/10Let equivalent resistance be rR. Then1rR =1r +1r +1r ....10 times∴ 1rR = 10r = 10R/10 = 100R ⇒ rR=R100=0.01RTalk to our academic expert!
