A) 62 V, 2 \[\Omega \]
B) 63V, 1 \[\Omega \].
C) 61V, 1 \[\Omega \]
D) 64V, 2 \[\Omega \]
Correct Answer: C
Solution :
For a closed circuit, cell supplies a constant current in the circuit. Equation of cell \[E=V+Ir\] For \[V=50\,volt\] \[E=50+11r\] ...(i) Similarly for V = 60 volt \[E=60+r\] ...(ii) From Eqs. (i) and (ii), we get \[r=1\,\Omega \] Substituting the value of r in Eq (i), we get \[E=61V.\]You need to login to perform this action.
