A) 0.5\[\Omega \]
B) 2\[\Omega \]
C) 4\[\Omega \]
D) 20\[\Omega \]
Correct Answer: B
Solution :
\[I=2\text{ }A,\text{ }H=80\]Joule,\[t=10\text{ }\sec \] \[\therefore \] Heat produced \[H={{I}^{2}}Rt\] \[80={{(2)}^{2}}\times R\times 10\] \[80=4\times R\times 10\] \[R=2\,\Omega \]You need to login to perform this action.
