Problem

A 2 kΩ2\,\text{k}\Omega resistor is connected in series with a 4 kΩ4\,\text{k}\Omega resistor across a 24 V24\,\text{V} ideal source. A voltmeter having an internal resistance of 1 kΩ1\,\text{k}\Omega is connected across the 2 kΩ2\,\text{k}\Omega resistor. (i) Calculate the reading shown by the voltmeter. (ii) Determine the percentage error in the measured potential difference across the 2 kΩ2\,\text{k}\Omega resistor due to the loading effect of the voltmeter.
