A) \[2\,\Omega \]
B) \[1.5\,\Omega \]
C) \[1.0\,\Omega \]
D) \[0.5\,\Omega \]
Correct Answer: C
Solution :
Internal resistance of the cell is given by \[r=\left( \frac{E-V}{V} \right)R\] Given, E = 1.5 V, V = 1.0 V,R = 2 \[\Omega \] \[\therefore r=\left( \frac{1.5-1.0}{1.0} \right)\times 2=\frac{0.5}{1.0}\times 2=1.0\,\Omega \]You need to login to perform this action.
