A) \[0.5\,\Omega \]
B) \[1.5\,\Omega \]
C) \[1.25\,\Omega \]
D) \[\frac{4}{5}\,\Omega \]
Correct Answer: A
Solution :
From the formula of potentiometer internal resistance \[r=\frac{{{l}_{1}}-{{l}_{2}}}{{{l}_{2}}}\times R\] \[=\frac{125-100}{100}\times 2=0.5\Omega \]You need to login to perform this action.
