A) exactly 10 \[\Omega \].
B) less than 10 \[\Omega \].
C) more than 10 \[\Omega \].
D) we cannot definitely say
Correct Answer: B
Solution :
\[{{V}_{AB}}=(I-{{I}_{g}})\,.\,\,R={{I}_{g}}\,.\,\,G\] where, G = voltmeter resistance \[{{V}_{AB}}=20\,V\] \[I=2A\] and \[R=R\] \[20=(2-{{I}_{g}})\,.\,\,R\] \[R=\frac{20}{2-{{I}_{g}}}\] \[\therefore \] \[R<10\,\,\Omega \]You need to login to perform this action.
