Main Question or Discussion Point

2 terminals of a battery are connected to 2 50k ohms resistor...but in open circuit.

i.e -

______
---------/\/\/\/\/\/---|______|--------/\/\/\/\/\/\/\/-----

______
the '/\/\/\/\/\/\/\/' are the resistors and the '|______|' is the cell wile '--------' are the wires.


What will be the potential across their terminals?

Another example of what I'm asking here is suppose we have 2 conductors submersed in a uniform electric field, one of the conductors has 50k resistance while the other has negligible; which conductor will gain more net charge when earthed?

Assuming that you're referring to the open end resistor terminals in your first question, the potential will be whatever the battery voltage is. The resistors have nothing to do with it unless they form a circuit. I don't understand your example, so maybe I'm misinterpreting your question. I don't normally think in terms of conductors and resistors as having a charge unless they form a capacitor. Conductors and resistors have a voltage drop across them when there is current flow.

The potential across the cell will be the unloaded cell voltage.
