Question

Statement I: Potential measured by a voltmeter across a wire is always less than the actual potential difference across it.
Statement II: Finite resistance of voltmeter changes current flowing through the resistance across which potential difference is to be measured.

• A. If both statements are true and statement II is the correct explanation of statement I.
• B. If both statements are true but statement II is not the correct explanation of statement I.
• C. If statement I is true but statement II is false.
• D. If both statements are false.

Answer 1

Answer: (A)

$ i_{1}=\frac{E}{R} R_{ eq }=\frac{R R_{V}}{R+R_{\nu}} $
$ i_{2}=\frac{E}{\left(R R_{V} / R+R_{V}\right)} $
