Questions
In the circuit shown, each cell has as emf of 5 volt and internal resistance 1Ω. Then potential difference between B and A is
a
12.5 volt
b
7.5 volt
c
10.5 volt
d
2.5 volt
detailed solution
Correct option is B
Effective emf of the circuit EC=(3×5-5) volt=10 volt ∴i=current in the circuit =104×1A=2.5A ∴VA-VB=(5+1×2.5) volt=7.5 volt.Talk to our academic expert!
