QUESTION #60 Voltmeter Resistance
Two resistance of 100Omega and 200Omega are connected in series with a battery of 4 mathrm~V and negligible internal resistance. A voltmeter is used to measure voltage across 100Omega resistance, which gives reading as 1 mathrm~V. The resistance of voltmeter must be ________ Omega.
