A) \[\frac{(E-V)R}{E}\]
B) \[\frac{(E-V)R}{V}\]
C) \[\frac{(V-E)R}{V}\]
D) \[\frac{(V-E)R}{E}\]
Correct Answer: B
Solution :
Let the current in the circuit \[=i=\frac{V}{R}\] Across the cell, \[E=V+ir\]Þ\[r=\frac{E-V}{i}=\frac{E-V}{V/R}=\left( \frac{E-V}{V} \right)\,R\]You need to login to perform this action.
