    Finding internal resistance from 2 circuits

    Makes sense. I guess I wasn't thinking clearly. Thank you so much for the help though!

    Finding internal resistance from 2 circuits

    A new problem has arisen when I use the r value I find to plug into other power loss formulas, ie P=VI and P=V^2/R the answer are different. Attempts: P=VI I=V/R P=60(60/(10+2)) P=V^2/r =60^2/2

    Finding internal resistance from 2 circuits

    Thank you so much! I enjoy that you are not exactly spoon feeding me the answer but instead going through the logistics of the concepts! I will apply those and come back if a problem arises

    Finding internal resistance from 2 circuits

    But the thing is that we have r+10 and r+4 equating to our resistance, so couldn't it be the r be the same number though?

    The voltage drop across the internal would be the same as we're using the same source and the only difference is the external resistor

    Finding internal resistance from 2 circuits

    Homework Statement A battery with an emf of 60 V and an internal resistance (r) is connected to a 10 ohm external resistance. The power lost inside the battery is 50w. The same battery is then connected to a 4.0 ohm resistance. The power loss is 200w. What is the internal resistance of the...
