A) \[100\Omega \]
B) \[50\Omega \]
C) \[20\Omega \]
D) \[10\Omega \]
Correct Answer: C
Solution :
We know that, \[p=Vi\] \[\therefore \]Current through the circuit, \[i=\frac{500}{100}=5A\] Potential difference across, \[R=100\,V\] \[\therefore \]Relation, \[V=IR\] \[100=5\times R\] \[\Rightarrow \] \[R=\frac{100}{5}=20\Omega \]You need to login to perform this action.
