AB is a uniform wire of length L=100 cm. A cell of emf V0 = 12 volt is connected across AB. A resistance R, cell of emf V and a milliammeter (which can show deflection in both directions] is connected to the circuit as shown. Contact C can be slid on the wire AB. Distance AC=x. The current (I) through the milliammeter is taken positive when the cell of emf V is discharging. A graph of IVsx has been shown. Neglect internal resistance of the cells.

Three resistors R1=3kΩ,R2=2kΩandR3=5kΩ have been connected to a constant current source as shown in figure. The current source supplies current I=2mA to the circuit. A voltmeter with RV=6kΩ internal resistance is connected, as shown, to measure the potential difference across R1. (a) Find the percentage error in the measurement of potential difference (V1) across. R1 caused due to finite resistance of the voltmeter. (b) If positions of R2andR3 are interchanged will the percentage error in measurement of V1 increase or decrease ?
