Vedclass · Answer

(D) The smaller the resistance of an ammeter,the more accurate its reading will be. An ammeter is considered ideal if its resistance is zero,meaning it measures the actual current flowing through the circuit without affecting it.Similarly,the greater the resistance of a voltmeter,the more accurate its reading will be. $A$ voltmeter is considered ideal if its resistance is infinite,meaning it draws no current from the circuit element for its operation.Therefore,an ammeter should have small resistance and a voltmeter should have large resistance.Thus,both $(A)$ and $(C)$ are correct.
