A) 3 \[\Omega \]
B) 6 \[\Omega \]
C) 12 \[\Omega \]
D) 24 \[\Omega \]
Correct Answer: A
Solution :
[a] Resistance of the wire of a semicircle \[=\frac{12\,\,\Omega }{2}\] \[=6\,\,\,\Omega \] For equivalent resistance between two points on any diameter, \[6\,\Omega \] and \[6\,\Omega \] are in parallel. So, the effective resistance is \[3\,\Omega \].You need to login to perform this action.
