A) Exactly \[4\Omega \]
B) Slightly greater than \[4\Omega \]
C) Slightly less than \[4\Omega \]
D) Zero
Correct Answer: B
Solution :
Voltmeter is not ideal so a small amount of current will pass through it. Hence voltage drop across R will 20 V if R is lightly greater than \[4\Omega .\]You need to login to perform this action.
