Resistances $$R1$$ and $$R2$$, each of $$60$$ Ω, are connected in series as shown in figure. The potential difference between A and B is kept $$120$$ volt. what will be the reading of voltmeter connected between the points C and D if resistance of voltmeter is $$120$$ Ω?

Question

Resistances $$R1$$ and $$R2$$, each of $$60$$  Ω, are connected in series as shown in figure. The potential difference between A and B is kept $$120$$ volt. what will be the reading of voltmeter connected between the points C and D if resistance of voltmeter is $$120$$  Ω?

$$R2$$ and RV are in parallel, their equivalent isR'$$2$$ $$=R2RVR2+RV$$ $$=$$ $$60$$ × $$12060+120$$  $$=$$ $$40$$  ΩNow, I $$=120R1+R$$'$$2$$ $$=$$  $$12060+40$$  $$=$$ $$1.2$$ AReading of $$voltmeter=$$ IR'$$2=1.2$$  ×  $$40=48$$ V

Resistances R₁ and R₂, each of $60 Ω,$ are connected in series as shown in figure. The potential difference between A and B is kept 120 volt. what will be the reading of voltmeter connected between the points C and D if resistance of voltmeter is $120 Ω ?$
