Homework Statement
We have to measure emf of a battery. We have to voltmeters. Each of them when connected alone across the battery, they read V1 = 0.9V and V2 = 0.6V and when both of them are connected to the battery simultaneously, they both read V3 = 0.45V . What is the emf of battery
Homework Equations
E-ir=V
The Attempt at a Solution
I don't know how to proceed...I thought the voltage across the battery will be it's emf when connceted without a load but it is showing different readings for the voltmeter
