Answered by qOooooooooOq

total EMF=3
total equivalent resistance=4*1/4+1
=2ohm
V=ir
3=i*2
I=3/2

qOooooooooOq: it is given that man added four cellsin series and last one is wrongly connected so

Karan828: oo then there is 3 cells rightly arranged then total emf should 4.5

qOooooooooOq: the wrongly connected cells EMF and right connected cell EMF is reduced from whole circuit but all the resistance will remain same

qOooooooooOq: is there is two wrong connected cell then we have to reduce also two rigghte connected with wrong ones cells but the resistance will remain same

Karan828: but.. why is it subtracted

Karan828: is that a rule to solve this type of ques

qOooooooooOq: it is subtracted because equivalent of that number is in opposite direction

qOooooooooOq: yeah last Monday my teacher taught me about that

Karan828: in which class r u?

qOooooooooOq: 12th
