If V0 is almost zero, identify the correct statement: |
A) The value of the resistance R is \[1.5\Omega \]
B) The emf of the battery is 1.5 V and the value of R is \[1.5\Omega \]
C) The emf of the battery is 1.5 V and its internal resistance is \[1.5\Omega \]
D) The potential difference across the battery is 1.5 V when it sends a current of 1000 mA.
Correct Answer: C
Solution :
\[V=E-Ir\]when \[V={{V}_{0}}=0\Rightarrow 0=E-Ir\] \[\therefore \]E = r when \[I=0,V=E=1.5V\] \[\therefore \] \[r=1.5\Omega .\]You need to login to perform this action.
