Homework Help: Calculating internal resistance of Papaya fruit battery

  1. Jan 16, 2017 #1
    1. The problem statement, all variables and given/known data
    Papaya fruit is split in half, with the help of two electrodes made out of two different metal materials, they are made into two chemical sources of electrical energy of same characteristic. These two sources are firstly connected to a resistor ( 9K ohm ) in series and then into parallel. If the ratio of these two voltages is 1.7, what is the internal resistance of each of the sources?

    2. Relevant equations

    3. The attempt at a solution
    V1/V2 = 1.7

    V1 = 1.7 V2
    V2 = V1/1.7
