A battery of emf E is connected in series with three resistances R, 2R and 3R. The voltage across 2R is measured with a voltmeter whose resistance is 10 R. What is the percentage error in the reading?

The battery of EMF 5V and internal resistance 20Omega is connected with a resistance R_(1) = 50Omega and a resistance . A voltmeter of resistance 1000Omega is used to measure the potential difference across R1 .What percentage error is made in the reading.

A resistance R is connected to a cell of EMF E and has an internal resistance r as shown in the figure. The voltage across R is measured using and ideal A voltmeter and circuit current is measured by an ammeter. A rheostat of negligible resistance is used to vary the current in the circuit. -Write down the expression for current in the circuit and voltage across R at any instant.
