A) \[\frac{20}{19}\Omega \]
B) \[\frac{19}{20}\Omega \]
C) \[\frac{10}{20}\Omega \]
D) \[\frac{29}{10}\Omega \]
Correct Answer: A
Solution :
The resistances \[2\Omega ,4\Omega \] and \[5\Omega \] Are connected in parallel combination. Therefore, resultant resistance is given by \[\frac{1}{R}=\frac{1}{R}+\frac{1}{4}+\frac{1}{5}=\frac{19}{20}\] or \[R=\frac{20}{19}\Omega \]You need to login to perform this action.
