    How do you find this
    Is there a particular method
    An example question would be where they give you the voltage of the battery. All the resistors have the same resistance. Then they ask you to find the potential difference between two points. What is the method for doing this!?

    Are you also given the current through the circuit? If so you can use Ohm's law (V = IR) to find the voltage dropped across each resistor.

    Well if the resistors are equal and in series, plus you know the voltage of the battery then the Pd across each resisitor is the same. So for a case of a battery of Voltage = V and where there are n number of resistors. The Pd across each resistor is: V/n.
