The given circuit is used to measure the resistanceR. The ammeter reads 2 Aand the voltmeter 120 V. AWhat is the value of R if theresistance of the voltmeteris 3000 2? If the resistanceof the voltmeter is takento be infinitely large, then.Ans. 61.2 Ω, 60 Ω. |

Answer» when the resistance is infinite of the voltmeter thenR=V/I=120/2=60ohmwhen it has some high finite value then the value of R will be slightly greater |
