## Homework Statement

A person measures 9volts accross the battery, 3 volts accross the resistor Ra and 4.5volts accross the resistor Rb connected in series (all three battery, Ra, Rb are connected in series) with a voltmeter of finite resistance. The resistor Ra=2M, and the battery has negligible internal resistance. Find- 1.The resistor Rb and 2. The internal resistance of the voltmeter.

[M=mega ohms]

## Homework Equations

- Ohm's law and Kirchoff's laws are only possible relevant equations.## The Attempt at a Solution

- I really didnot get this. Shouldnt the voltages at the two resistors add up to give battery voltage?[source of the question- tifr gs 2010]
