Question

Consider the following statements.
$1$. The resistance of ideal voltmeter is infinite.
$2$. The resistance of ideal ammeter is zero.
$3$. Tangent galvanometer is used to measure steady currents.
$4$. Law of electrolysis is given by Faraday.
Which of the statements given are correct?

• A. $1,2$ and $3$
• B. $1,2$ and $4$
• C. $2,3$ and $4$
• D. $1,2,3$ and $4$

Answer 1

The correct option is D $1,2,3$ and $4$

Ideal voltmeter has infinite resistance whereas ideal ammeter has zero resistance. Also, steady currents can be measured with the help of tangent galvanometer and Faraday gave the law of electrolysis.
Hence, all the statements are true.
