0.241: A series combination of 2K resistor
and IKW resistor, is connected
across a battery of emf 6V and
negligible internal resistance. The
potential drop across 2K12 resistor,
is measured by
(1) a 30K(2 voltmeter
(ii) a 1 KO voltmeter and
(ii) both these voltmeters are
connected across it. If the
voltmeter readings in the three cases
are V, V, and V, respectively,
arrange these readings in descending order.

How will the three readings compare with one another if the potential drops were measured
across the series combination of the 2 KN and the 1 KN resistor, i..e across the points A and B?
