Given below are two statements : One is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : For measuring the potential difference across a resistance of $$600 \Omega$$, the voltmeter with resistance $$1000 \Omega$$ will be preferred over voltmeter with resistance $$4000 \Omega$$.
Reason R : Voltmeter with higher resistance will draw smaller current than voltmeter with lower resistance.
In the light of the above statements, choose the most appropriate answer from the options given below

Evaluate the assertion and reason about voltmeter selection.

Assertion A: "For measuring PD across 600 $$\Omega$$, a voltmeter with 1000 $$\Omega$$ is preferred over one with 4000 $$\Omega$$."

INCORRECT. A good voltmeter should have high resistance to draw minimal current and cause minimal disturbance. The 4000 $$\Omega$$ voltmeter is actually preferred because it draws less current and gives a more accurate reading.

Reason R: "Voltmeter with higher resistance draws smaller current."

CORRECT. By Ohm's law, for the same voltage, $$I = V/R$$, so higher resistance means less current.

A is not correct but R is correct.

The correct answer is Option (1).
