Sry friends but equivalent resistance is :- 1/Req = 1/R1+1/R2+1/R3.........=19/20 ....this what we get answer but friends we also have to reciprocal it as 1/Req is there...so by reciprocal it we get the correct total resistance ...that is 20/19 ......hope u all understand

19/20

Divyanshu Mishra 6 years, 3 months ago

Total resistance will be equal to 19/20 Since,resistances are combined in parallel hence total resistance ,R=1/R1+1/R2+1/R3+1/R n SOLUTION: TOTAL RESISTANCE =1/2+1/4+1/5, Lcm=20, Total resistance =10+5+4/20=19/20 If you all friends satisfied with my answer ,Show your satisfaction by giving THANKS by pressing Thanks icon given bottom to my answer
