A) equal to 5\[\Omega \]
B) greater than 5\[\Omega \]
C) less than 5\[\Omega \]
D) none of these
Correct Answer: B
Solution :
Here,\[I=4\text{ }A,\text{ }V=20\]volt, so \[R=\frac{V}{I}=\frac{20}{4}=5\Omega \]Since, voltmeter is connected in parallel with resistance R, the effective resistance of this combination is\[5\Omega \]only, the resistance R is greater than\[5\Omega \]because total resistance in parallel combination becomes less than individual resistance.You need to login to perform this action.
