QJEEM24Phfbfc: JEE Main 2024 Physics - Class 12 JEEM24Phfbfc Solution: Two resistance of 100 Ω and 200 Ω are connected in series with…

Two resistance of $$100\mathrm{\Omega }$$ and $$200\mathrm{\Omega }$$ are connected in series with a battery of $$4\mathrm{V}$$ and negligible internal resistance. A voltmeter is used to measure voltage across $$100\mathrm{\Omega }$$ resistance, which gives reading as $$1\mathrm{V}$$. The resistance of voltmeter must be _______ $$\mathrm{\Omega }$$.
