    Extremely Difficult Circuit Problem involving a potentiometer

    I need some help. In this circuit does V0 = R + R1 +R2? And can someone elaborate on putting the resistance as a function of x and L?

    Help with applying Kirchhoff's Law to a circuit

    If you look at the image then another person posted: How do I determine what the voltage is between A and B or between B and C? I guess I am just confused a bout the multiple voltage and how they are moving toward the center.

    Help with applying Kirchhoff's Law to a circuit

    I have been working the problem and after applying Kirchhoff's Law I ended up with 3 equations and 3 unknowns (which are I1,I2 and I3). I can easily see that if each current was .01 that would be a solution but then it wouldn't agree with the nodal law for the middle node. I am confused.

    Help with applying Kirchhoff's Law to a circuit

    I am not the best physiscis but I think it means that there is no change in the potential difference therefore the voltage and current remain constant? the voltage drop across R4 is equal to the total Voltage?

    Switching from parallel to series and keeping restistance the same.

    Homework Statement Two resistors of X and Y are connected in parallel with one another and in series with a 200 Ω resistor and a battery \epsilon=1.5 V and internal resistance r=0.5 Ω. The resistance of X is 100 Ω. When Y is disconnected from X, an additional resistance of 50 Ohms must be...
