A voltmeter having a resistance of 1800 Ω is employed to measure the potential difference across 200Ω resistance, which is connected to dc power supply of 50 V and internal resistance 20Ω. What is the approximate percentage change in the potential difference across 200Ω resistance as a result of connecting the voltmeter across it?
